Server Errors

Currently using Sponge Forge with FTB Direwolf20 1.10.2. Not sure what is causing these errors. The only plugins I have are ultimatecore and pex.

Something in the modpack is arguing with Sponge. Whichever mod belongs to.

I think it’s an issue with sponge’s async lighting, see my post here:

I’ll have a look. Thank you for your replies.
