Got that after trying to relog on server after quitting for dinner(not from crash)
only thing new is that not long before exiting, I placed 2 ThermalExp Cel and an Enervation Dynamo
got the same CTD multiple time, I manage to join the server, see ~3seconds of far map, then CTD.
Only Client is crashing.

I can go on my server as long as my clients do not load my house chunk.
As soon as the chunk is loaded on the client, CTD with above crashlog

Setting EnableShaderEffects=false in cofh/core/client.cfg get me https://pastebin.com/wKvZ4Ky3
