Okay, so me and a friend have been playing tekkit on the same world for about a week with no problems, we made a base inside of a dimensional door. (the ones you make not ones you find) we just played last night. worked perfectly fine. and now, it crashes whenever i try to launch it. the error says something about the dimensional doors. log below:
