We've received some issues from non-English players in 0.5.038 that resulted in problems with damage, movement, etc.
Today we were able to repro this bug (finally!) and find an immediate fix for players while we prepare an official hotfix to be released soon.
You can correct the problem immediately in 0.5.038 by changing your Windows Language settings to English. That should fix the issues mentioned above.
Language influences controls!? Yep, the issue had to do with periods being converted to commas.
We are working on an official hotfix to go out very soon.
Thanks again
