If you give the console output, then he might be able to do something to fix it. Otherwise he has to setup a game to test it and find it out for himself, so it'll be 5 times longer before he takes the time to do that and try to get it fixed.

rotten food appears to cause a loop of "taking",no expection error though.

RE: Rotten food. I normally see this because their inventory is full. Call them over and have them clear their inventory. Then see if they still have problem taking the food.

tried clearing his inventory the moment i saw the loop,was hoping they'd drop it,they dropped a bunch,just not the cake in the loop.
