There is no mods, only InvTweaks and SkinServer. I don't see any icons from mod, i can only sort by R and see some time text like "/u273r/u421b/"(Thats not real text was in game). It's in singleplayer. Sorry for bad English, i'm from Russia.

You installed the mod incorrectly, and are not using the latest version which fixed the translation files.

I just leave latest version in /mods folder. Forge - latest. Installed forge with Installer. Using Magic Launcher. R working only if i not in inventory. Please help, i need to sort items in chests.

Sorry for wasting time, i really has an invalid version.
