could someone please help me? i'm using minecraft 1.7.2, but whenever i try to enter an existing world or try to create a new one, it keeps going back to the main menu screen, and if i do enter the world, all my progress gets reset. i think its a problem with forge, because i did some experimenting and i found out that this happens when i use anywhere from forge version 1000 to 1023. it behaves fine with the forge versions for minecraft 1.7.2 before that range, but the problem with those versions like forge 998, is that they don't run with most of the 1.7.2 mods because they are outdated............Could anyone give me a solution for this problem.
