Minecraft General

Do i need to return a list of ItemHandlers?

I dont even understand what type of value is this. What LazyOptional do, how it works and how i can get ItemHandler from this. 

i couldnt find debug but my mate said just send this     latest.log

Hi I'm trying to start up a modded server that I've been running locally fine for a few months. I've attached the full log but its stdebug.logalling with the same last line each time. [Server thread/INFO] [ne.mi.co.AdvancementLoadFix/]: Using new advancement loading for net.minecraft.advancements.PlayerAdvancements@4a0990e6   I've tried to run a backup copy of the server as well but this has the same issue so I'm assuming it's some issue local to the machine thats trying to run the server.   Thanks for any help you can provide or if you need anything else.

That is not the debug.log from the logs folder. Where did you look?
