Game started being buggy? Sims 4

Hey everyone - basically I'm coming on here to just say my game has been so freaking buggy lately. This hasn't happened before and it just started acting weird. I think it was probs a month ago or so I have no clue. First, it was the random light bug where when my sims leave the lot, the power gets cut off and doesn't turn back on, so I have to exit the game in order to have the lights turn back on. They don't use the dishwasher either. I try to do the load dishwasher but the icon just disappears. Also, when you look in the mirror that's near a window, the wall just looks cut? I would have to show a picture if anyone wants to see it. Also, when my sims try to load the washing machine the little clothing bag turns to the side when they're walking towards it. My game overall is fast but it gets so laggy because of how buggy it is. I would delete the sims file but I don't want to lose my progress with the family I have now because they're just such a pretty family. I have no idea what to do. I tried taking out my mods to see if that would work but it doesn't. I still get LastException files even though I deleted MCCC. Has anyone else experienced this? Does anyone know if Origin will do an update to fix the bugs? Please help!!
