Not listed as server and client side

It needs to be installed on client and server but wont kick players if they have it installed but join a server without it. Then they just crash when opening the creative menu

Where specifically does this come up? It's marked to the best of my ability on all platforms that offer marking mod environments AFAIK.

just when u try to join a server, it doesn't kick you for having a mismatched mod list, so it crashes you when u open creative inventory(may crash when picking up item but I haven't tested)
