With only a short title to go on it is hard to know what your problem actually is. You don't need to remove Italia DLC, ProMods 2.27 works fine with it (and ProMods 2.30 onward will require it).

Please review How to report a game crash.

It wouldn't be a completely invalid thing for a beta-tester to highlight, generally 'tree walls' should not be in use so close to the player. However it is a feature suggestion rather than a bug, please stick to actual bugs here.

Well what do you expect when you report non-bugs?
Besides, we're fortunate to currently have several testers able to keep on top of the forum reports, sometimes we lag behind by weeks!

Everywhere has been tested to some extent, but you can always find more bugs

Keep it up.

These bugs are one issue in the bugtracker so topics merged.

Are you playing with any other mods than ProMods + RusMap? If so try without them

No trace of a crash in this game log, make sure you upload/save the game log after a crash before starting the game again.

We need your game log to help you - please read How to report a game crash.

Topic split, without your game log we can't see if it's the same problem. So please try with ProMods only enabled and post the game log!

Sorry but with that many mods it's up to you to find out which combinations work. We can't tell just by looking. Remove all mods except those you know will work together, then add the others back in one by one to find the culprit(s).
