There is a ticking entity crash that prevents me from joining the game. The logs say it is connected to flax somehow. I don't know how to reproduce it, but it has happened twice so far.
This one happened immediately after I opened a bundle full of items, the contents of which I don't remember. (I don't know if this is relevant.)
