Pictures:

I've added a != null check to all the packets just to be safe, but I don't think this should be necessary? Interesting that this has never happened before

This is unrelated to BL, no need to add a null check @TheCyberBrick. You see the vanilla packets having the same issue in that log. This is can happen when a connection is closed while there are packet tasks in the queue, consequently getting processed after close.

Issue is still occurring. It turns out it's connected to tropicraft.

Tropicraft/Tropicraft#254

The Betweenlands is not related to this issue.
