I keep having problems with some tables being served. Sometimes my staff just skips a table and starts serving the next, the following and so on, and this table never gets served. It also happens when I use the command "Prioritize Food", their food never comes out. I don't think it's a staff problem since most of them are well trained.
Also, today a table got their food served but they never ate it and got the message "I'm not very happy about the wait times here...". They left with one star.
I repaired the game a little after installing the pack since I had problems with the game not saving customized clothing for the staff (I still have this issue, but it looks like it works if you edit the premade clothing options) and I have no mods.
