dried frostburgers create massive lags

I have a storage bin with 17000 dried frost burgers.

- If I destroy the storage bin, or let them drop out of the storage bin, the game is not playable anymore. The computer is calculating something and I have 1 fps every minute.
- If I hover over the storage bin, frame drops to 1fps or less.
- dups can't get dried frostburgers. they start to collect, then stop. in time they run out of air.
--- ok after a while they are able to get them. also they can carry only one dried frost burger.
