Problem Server crashes when specific players join

[Cozza]

Hey guys,

Having an odd issue where specific players are crashing the server when they join. I don't think it's a chunkloader thing, possibly corrupted chunks although MC Region Fixer reports no issues.

Any ideas?

Are you by any chance running Forge Multipart on a MCPC+ server? Currently these two do not play nice together.
