We are having a problem on our server that water storage devices will only store 12 and 24 ml of water regardless of self filled or manually filled. 
if we try and fill in game with a bottle or canister it give us a (Kicked: RPC Error in MoveItem) message and kicks us. We have let collectors, and pumps go for 2 days now and only got either 12 ml of fresh or 24ml of salt water. Were kinda at a loss. 

our plugins we use are:
Gather manager
Stack multiplier 
and stack modifier.
