Greetings.

After 1.39 update some strings in the game UI have been replaced, which made the whole interface kind of gibberish.
In some cases it's just annoying, but some of them are crucial. For example, I can't compare weapons by damage they can deal.

I reproduced the issue for English and Russian localizations.
Seems like message IDs have been messed up, because translated strings match.

P.S.: GOG doesn't allow me to post links or attach screenshots for some reason. :(

I'm experiencing the same bug.
I've attached example screenshots.

Does anyone tried sending this as a bug report? Its very frustrating cause apparently this bug only happens on the GOG version of the game

Well the german version also has problems with missing itemstats (like damage for weapons) and some randome text.

The issue seems to be fixed in 1.39A patch.
