 mid dungeon my grid2 vanished clique stoped working and its only affecting my alliance shaman, all my other toons and my horde shaman all have no problems at all

Try with all other addons disabled, you can test the issue with another profile. But if clique was not working too i think the issue is not related to Grid2.
