It was as simple as that. The game closed immediately after the world generated in the Shivaxi RLCraft modpack. The console says, "java.lang.OutOfMemoryError." I have no idea what is happening, I just want to play this modpack but nothing at all is working right anywhere. Your basic answers will probably not solve the issue.
The launcher Console said this:
[B#456] SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
[B#456] SLF4J: Defaulting to no-operation (NOP) logger implementation
[B#456] SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
