My local server crashes with java.lang.NullPointerException: Ticking entity with both makeEventsSingletons and enderio active.

Debug log with crash and makeEventsSingletons=true and enderio installed
debug-1.log.gz
Debug log: All good with makeEventsSingletons=false and enderio installed
debug.log
Debug log: All good with makeEventsSingletons=true and enderio removed
debug-1.log.gz

I've built from source, tested it and it works! Thanks for a quick fix!

Np, curseforge is having some trouble validating the file.
