Correct, it modifies the same files, so it's incompatible.

it goes back to default values when i have RT56 installed

Probably not. I'll get around to updating it this weekend. I've just been a little busy.

it is work on new version?

Assuming it doesn't affect any land equipment, yes. Otherwise, no.

Would this work with RT56?

Yes, it should.

Does this affect armored cars as well?

They'll simply apply the same reduction, but won't stack. So whether or not you have both or either of this or it's parts, the outcome will be the same; a 1/3rd reduction in base cost for affected items. This is just a combo pack for all the land specific stuff so one can get it all with less clutter in their mod lists, along with added equipment for things that don't fit in any of the other categories like trains. Assuming you got the whole series, by using this instead of their individual parts, you'd have a group of four mods instead of eight to activate. Along with cheaper trains.

What happens when you load this mod plus your other Land Build Cost Reduction mods? Such as running with Infantry cost production reduction, etc?

If they don't touch base game equipment, then it'll likely be compatible. So if it just adds equipment, it would also be compatible.

Is the mod incompatible with KR and KX? AFAIK the mods don't modify anything about production.

If it has custom or changed equipment from base game, this isn't compatible.

Is it compatible for EAW?

This applies to the A.I. as well, yes.

Did it work for only player or both player and AI????

They don't need changes to be compatible with 1.9, so they will still work as intended when activated. There shouldn't be any issues when using them.

Thank you it seems to work well now, no crashes at all though it seems to register the lower support equipment, artillery, and buildings as not updated in the launcher

I just updated it, so it should work. To be sure, install the direct download version. If it's still not working get back to me and I'll help

I think la resistance broke the mods :/

does anyone tried this with Road to 56 mod?

If it changes base game equipment files, likely not.

does this work with fuhrerreich?

sorry for it

No, as MDawn uses new equipment and overrides base game stuff.

is this support MDawn?

As far as I'm aware, no

Does the collection work with millenium dawn?

If it changes base game vehicles no. If it just adds new ones, yes, probably

does this work with Historical Vehicle Overhaul?

Yes because it doesn't change land equipment. It does change ships, so my naval mod wouldn't work.

Is this compatible with Kaiserreich?

Thanks for the quick answer.

From what I could immediently guess from the images and lack of information on what techs are expanded or changed, I'm gonna give a hard maybe. Seriously though, as long as the land tech/original equipment is unchanged, it should work just fine. Otherwise there is no garrentee.

Is compatible with Road to 56?

100% yes

is it compatible with your other two lower building cost mod known as lower building cost (air) and lower building cost (naval)

Sure of what?

Are you sure?
