So, recently I was playing EMC and I switched to smp8. In the process, it disconnected me and a screen popped up saying, Internal Exception: io.netty.handler.codec.DecoderException: IntArray with size 2 is bigger than allowed 1 I'm not a very tech-ish person, so I have no idea what this means. It pops up whenever I try to log on. Help?
Hm...maybe check the client version in the launcher? It's part of the profile, which is the drop down in the lower left corner. EMC should be compatible with everything 1.9 and higher so this might be a long shot.
