Steps to repoduce

• join vanilla server with a client(26.0.55) with only 'BetterAdvancements'
• client crashes

logs: crashlog

Tried to compile with forge:27.0.59 and mcp:20190718. Can confirm it does work with gradle:runCLient. Compiled output for some reason not.

Update:
as of 1.14 the access transformer file need to be called: 'accesstransformer.cfg', custom at names are not being used anymore. Got it working

Should be fixed with #67
