Issue:Internal Exception: io.netty.handler.codec.DecoderException: net.minecraft.ResourceLocationException: Non [a-z0-9/_-] character in path of location: rs_nouveau:archwood_fence_gate\u0012minecraft:charcoalXars_nouveau: smooth_sourcestone_stairs\u0019minecraft
I wanted to add some mods, but the server won't start
Seeing this, I removed all new mods and their previous settings
Now the servers start, but no one can enter without this error appearing

Remove arsnouveau from server and client or try an older build
