Server crashes adding Carrier mod. Attached is crashlog
crash-2020-12-26_07.01.57-server.txt

Can you reproduce this with just Carrier? Seems to be crashing with WorldEdit, I'll look into this. Thanks for the report.

I also get a server crash caused at least in part by Carrier. Removing Carrier fixes the crash. Interestingly there are no problems in singleplayer or LAN environment. Unfortunately I don't know much about Fabric or Mixins yet, so I couldn't make much more of the crash log except figuring out that Carrier has something to do with it. Possibly conflicting with Charms? But then again it's weird that it works in singleplayer. https://pastebin.com/m1PEfeCf

Edit: List of mods I use on the server https://pastebin.com/sCdCcyiT

Should not be an issue anymore, thanks for the report.
