i crash ounce i start a run with only this mod and the two necessary ones

Can you post the crash log please?

This made my game crash as well, but I discovered it happened when I created a new profile and started my first game. I suspect it has to do with the tutorial messages that appear the first time, went through that without the mod and then it worked perfectly.

It would help to get the crash log. You can find it by clicking on the game in Steam, select "Manage>Browse Local Files", then you can find the log file (SlayTheSpire.log) under sendToDevs/logs/.

I don´t have any problems running this mod with : Infinite Spire, Replay The Spire, Clawfect, Conspire and Treasure Hunter. Played a lot of games with this combination and no problem at all. I was just wondering @Sagil is there some config possible for max Evolution unlocked or to set it lower?? In Treasure Hunter I was possible to lower my gold rewards, because i farmed a lot but still have many evolution points, but don´t want to disable this mod because i like it :) Thanks for reply

Not in the interface, but you can manually edit preferences/evolution in your SlayTheSpire folder to set current evolution points to whatever you like.

Are you using any mods that modify ascension level?

Sorry, I'm not sure. I'm running with about 90 mods at the moment.
I was hoping this was a known conflict. I could list them all, if you'd like.
I've removed Rumiabox (the last mod I installed) the problem hasn't returned.

That makes it tricky. I suspect that something is messing up AbstractDungeon.ascensionLevel, setting it to a value so high that allocating an array of that length causes you to run out of memory. If it happens again I can add some safeguards against the crash, but that won't address the root cause.

Ah, I was running ascension 1. If that happens again, I'll turn off that mod.

There are some weird edge cases involving alternate Act 1's and Custom/Daily Run Modifiers in which it's possible to obtain a second Axolotl at the start of the game. I'm not sure what exactly the conditions are for this bug to happen though.

Haven't been able to reproduce, but added a safety check that should hopefully prevent it from happening again.
