I'm using ItemsAdder for the resource packs if it matters.
I'm getting kicked from the server whenever the resource pack loading is skipped by this mod. using the following software versons:
paper: 1.20.1-84
velocity: Velocity 3.2.0-SNAPSHOT
BungeePackFix: 1.1.1 (although this reports in logging as 1.1.0-r3, i double checked and redownloaded 1.1.1 from this GH and it still does this)
ItemsAdder: 3.5.0c-r2
LoneLibs: 1.0.25
