Additional context

so i just did some more testing after thinking i blamed the wrong mod for the crash and i'm even more confused than before. If i run just this mod, it seems to work fine, but if i try and use this mod and the mod menu mod, then is crashes every time. running it with any other combination of the mods i listed works fine, but the second you add the mod menu mod, it crashes during world gen

ok, this seems to be an issue with mod menu and not C2ME
