From the looks of it, it is a hard-mod (replaces game files) that is specific to the listed game version ( 0.9.0.18 / 0.9.0.19 ) and should not be used on any other version. If you do use it on other versions, you need to accept that there will be bugs.Seeing how that entire page is in Russian, how do I know it's working? It's not given me any errors but my trait screen doesn't look like the screenshot they have posted. Is it one that requires UMM?
Until they or someone converts it to use the Modding API (Vanilla or UMM; or both) it should only be used on the listed version.
