Description

Quite simply when anyone on the server opens a beacon the server crashes, here's the error log: https://pastebin.com/dRcAEiLw

Not sure when this started since my server is fairly small. Can't deny it might be related to something other than Arclight but if so I could not find what.

In addition to this, I had crashes related to wandering traders, had to disable them. From what I seen it seems to be related to them drinking invisibility when they want to be gone, I was able to kill them by changing time but. As soon as I hear a slurp the server crashes and after that if I enter the area and look in its direction it likely crashes too. Here's a crash log: https://pastebin.com/YC0xyMZY

Step to reproduce

Open an activated beacon as simple as that. Load a wandering trader that has been around for some time.

No response

Also a question, is there a way to get dev builds of Arclight for 1.20? I've only seen 1.18 versions and it seems like a lot of the issues are fixed in dev builds but not the one at the releases page. I think I might switch back to Purpur for the next season for stabilities sake at least for now, but I love the performance boost from Lithium and having the ability to include both mods and plugins is amazing.

Ran this without Ferrite or Lithium and had the same effect. Java 21

I had a similar glitch, which made a wandering trader stop the world from starting. Best advice I have is using a tool like NBTExplorer and delete the wandering trader from your world if and when this happens.

I have the same problem as you. I also tried removing every plugin and mod from the server but the problem persists also in version 1.21. Furthermore, the brew stand does not work correctly and instead of creating potions it duplicates the objects placed inside (e.g. redstone, nether wart, magma cream...)
