So I'm getting this warning spam in my console since I downgraded from 1.20.6 to 1.20.4 from viaversions saying "[10:10:01 INFO]: [packetevents] Unable to grab ViaVersion client version for the player!"
I asked my Host and apparently it was related to itemsadder, I realized it myself later cause I faced some problems loading the tpack while joining on different versions, is there any solution for this, or what is the best version to use on 1.20.4, cause when I use the latest version it doesn't work and currently I'm using ItemsAdder_3.6.4.jar
Thanks
