hello.
if possible, can you add a quickstack mod (https://www.curseforge.com/minecraft/mc-mods/quickstack) ?
i tried to suggest this mod directly through the server site, but I got rejected due to the fact that the mod is client-side. but at the same time, trying to enter the server with this mod - the server does not let you in with this mod, and asks you to delete it.
thanks for your great work.
