Sim are not being seated at restaurants

This wasn't an issue until about a couple weeks ago. Whether I use the Lovestruck or Dining Out pack for dating events, the host won't seat my Sims upon requesting a table. The host will act like they're trying to find a seat, then activity will disappear. 

It also happens when my Sims aren't on dates and arrive at restaurant in a group. When a Sim requests a table, only that Sim will be seated, not the group.
