I just had this glitch as well. I had made it a point to explore vast swathes of the map, especially the border to the Great Black Swamp, and loaded the game only to find that almost all my map progress had been erased and all discovered locations were no longer marked. I can only pray that my camp near the ATN is intact, as it had all of my guns, ammo and medical supplies in it.

I had this problem, so I restarted - I'd lost access to the last chance canteen and was having to go into the DMC just to get food I didn't have to scrounge for. Also lost access to Hatter's place, and the names on the map ie the Junk Market.

Next game started really well(got a compound bow early), but now it's unplayable because I only have one action per turn, regardless of my condition.

It's the autosave that's doing this, turn it off and remember to save manually and frequently.

me 2 same issue. Game ♥♥♥♥♥♥ up an amazing run, it's very frustrating.

First of all, I apologize for the issues! There have been several reports of this since the v1.15 patch, so it appears the autosave fix I applied didn't fix everything.

Unfortunately, I still don't know exactly what causes this issue except that it typically involves long-term games. Simply exploring most of the map didn't seem to cause it for me, but maybe my tests weren't long enough.

I have heard of one example where this happened after the player crafted boiled water many times in succession. Does this sound familiar to anyone? I.e. "farming" water or tannin tea?

Once I can figure out how to cause the bug reliably, it's usually not hard to fix. But until then, I'm just stabbing in the dark :)

My autosave issue back in March was on a relitively short term game, actually. Only about 2-3 hours of gameplay, only really explored a lil bit of the area between the forest village (forget the proper name) and DMC.

Interesting. And even this disagreement with other data might be a useful clue. I.e. it's not the game length nor map reveal amount, but maybe just the probability of the error that increases in those cases.

Still not sure why autosave would cause this and not regular save. Iirc, it's the same code used in both, just autosave uses it every turn.

Unless it's something outside the game interrupting the save process, and autosave just makes it more likely due to saving more often? E.g. Flash or a virus checker is changing the cookie location mid-save?

No smoking gun, but eventually, enough of these disparate clues should resolve into a clearer picture!

I think it only happens when loading an autosaved game. My game was 'corrupted' after sleeping IRL. Question is if it can corrupt only when exiting and reentering the game, or if it can happen without exiting the game, for example trying to save scum something with autosaves.

I don't think I've seen enough specific info to know if this only happens when exiting and reloading the game. Though, that would be useful info.

And speaking of save-scumming, do you use anything like an external save manager? I never really thought of it until your latest post. And I don't think such a thing would cause problems.

But depending on how the save manager works, and if it tried to copy/paste files while they were being written, I could see that very easily creating this problem!

I used nothing external when my game went kaput.

Yes, I farmed ~3K$ with sterilized water (while soaking up some equipment from the junk yard, mainly nanomedpacks and weapons). Map was completely gone, as were all my campsites.

Only thing, apart from the water crafting, which might be slightly off is that I moved a communal trash barrel fire from the campsite of one hex to the ground (to make more room there for my stuff in the campsite).

Save went kaputt when saving in near detroit, outside the gates on a hex adjacent to the junk market.

Save-game file shenanigans: copied it to a different folder using windows explorer repeatedly in a prior play (till the game killed of the character by gastroen<something>), but didn't do it in this attempt (had started a fresh game and played for ~5h or so in one run while waiting for some servers to do their job).

One suggestion as a band-aid:
Maybe move the old save file to the side first, then write the new and in case the new file being bigger (or not excessively smaller) after the save, compared to the backup, then it should be fine and the backup one could be unlinked.
In case the new save one isn't bigger (or excessively smaller, as the map is lost) dump the memory to a file in that folder and inform the user to send it to you for debugging?

One possible place to look: could it be that the file, at some point, exceeds the maximum configured storage space allocated by flash? I vaguely remember having seen a requester from flash asking me to give the app more room for the savegame...

Please hunt and exterminate that bug as it is really annoying for a save to be taken away by it, especially one of a game that runs good.

i just had it happen to. i went to save and exit and it froze on saving, then after REALLY ramming that left mouse button did it go away. however all of the southern part of the map is now un explored for me and my camps are gone, the only theing of value being a laptop with 2 hacking programs. however i have still been able to access the junk market, not hatters which was my base btw. i havent tried the last stop store. btw the c-store at dmc sells water for about 10 bucks cheaper than last stop. also the run time of, well this run, is over 5-6 hours if that helps dev.

Why would you buy water with so many water pools available?

to save time

2 times out of 3 (dont remember what I was doing in third case) this happened while I was hunting deer and dogman with bow. Autosave was on.
