Why change name for textures ?

It does not require translation to different languages. Let it be so for English language. Change : OverlayТёмно-голбуй.png -> OverlayDarkBlue.png
For all.... Thanks.

If needs...

Looks like someone's using localized name where unlocalized one should be.

Looks like this has been fixed, thanks @unpairedbracket.

Thanks )))
