I broke an (empty) fluid-upgraded cabinet to put it in another place, i got the cabinet and the upgrade back... After setting it down again I can't apply the upgrade any more.
Even new cabinets and upgrades won't work. It appears I can't make fluid drawers ever again on this map.

What I've tried so far:

• spawning in completely new items
• restarting the client
• restarting the server

There is no log messages on either client or server that are related to RFC during that time.
