Hi there! This past week, my players and I have started having some crashes that may be related to your mod. These have all happened on a multiplayer server and have caused the client to disconnect (but have not affected the server itself). The server logs haven't had anything unusual in them, and I do not have access to the client logs (but I'll try to get some).

I think in every case, the player that crashed has teleported to another player or a Waystone and crashed upon loading the chunk with the lights in it. Some have many lights, others have very few.

Thanks for reporting! Patch will be available soon.

We've gotten another crash that doesn't seem to be the same, but may be related?

Let me know if you'd like me to make another issue for it. Thank you!

That is related yes! Just got it fixed as well as original issue in Fairy Lights 2.1.9
