Anything else?

(edited to correct the mod version option)

Are you running it on client by chance?

[ielenia]

I am running it on client, mainly so I could (hypothetically) use it on a LAN server. I tried it out on a dedicated server and it doesn't crash there.

[OoLunar]

I can reproduce the issue server-side. Has there been a fix for this yet? I can go test it if required

[nhasdarjian]

Hey, this plugin still crashes on start due to mixins. There are two pull reqs that attempt to fix this problem, any chance we can get a review? I'm using Polymer 0.4.5 and FW 3.0.0 on fabric-server-mc.1.19.4-loader.0.14.19-launcher.0.11.2.jar. Thanks!
