Yes, twice a day. The prisoners show up but get no food.
I've also tried removing the kitchen and rebuilding it. It then worked for one meal cycle, and then stopped again. There's no feedback that I can see to indicate why. All appliances are connected to utilities.
I tried the serving tables in the lower position, no good.
The cooks are not cooking. The food enters the kitchen, but cooking does not happen.
On one of the serving tables, the stack of trays was 100% damaged and I was unable to remove the trays so I replaced the table- that seemed to be unrelated however, as the kitchen continued not to cook.
What would be good to see is a screenshot of the cantine area in deployment mode as I am guessing that with all the rubble that is about there is parts showing as no access if that is the case then you can remove the rubble from the game by editing the save game file
