Otis mod don’t work. I used Opis-1.2.5_1.7.10.jar (it is last version) but when i staring client or server i see error “Forge Mod Loader has not found a problem with you minecraft installation. The mods and versions listed below could not be found” MobiusCore: [1.2.5,1.2.5]"
May be you can say another mods for debugging? Microsoft Visual Studia ?=)
