When the Invisible Light Block from the Feral Flare Lantern seems to be near or in flowing liquid (water/lava) my server performance keeps dropping and when the chunk is loaded the server often crashes,

MC-Version: 1.16.1
Forge: 32.0.99
Mod: 2.3.1 alpha

Error-Log: https://pastebin.com/XAG0ZbqT

I'm having trouble replicating the issue with just torchmaster. Are there any vines around the lantern? The crash indicates some issue with vines.

I don't know what exactly the issue could be. I'm unable to replicate this locally but considering I got 2 reports within hours of each other for the same problem, there might be something more behind it. This is pretty much a shot in the dark, but it might help. I've removed the invisible block from the mod and replaced it with a light emitting air block that uses the actual AirBlock class from minecraft. Please update to Torchmaster 2.3.2-alpha for MC 1.16.1 and let me know if the issue persists.

Fix seems to work! No longer crashing. Will try to test it intensely under different conditions.

Many thanks for the fast hotfix !!!

I'm happy to hear this is working for you. I'll be waiting for a response in #133 from @BlazingPL if the fix also worked for them, but if I don't hear anything from you guys, I'll assume it's fixed :)

Closing this since I got the confirmation this was fixed :) If there is still anything that looks like a similar issue, please open a NEW issue. Thanks!
