Bar glitch

Hello, there's an error whenever my sim goes to order a drink. The sim orders, pays for it, they sit down. The reocurring issue is that once seated down enjoying their drink, out of nowhere, the games glitches and every sim sitting at the bar and bartender glitches out and reverts to no action. They stand there like "so what am I doing now?". It's been a long time, I hope EA team can fix this! Thanks
