Screen glitching
Some parts of the house look transparent in my game. This happens in Sunset Valley and Bridgeport (I never played the other worlds) whenever my sim is inside her house. I don't know if this is a general indoor thing (I don't recall seeing this at other places) but it always happens when at home. I play on Mac M2 if that helps.
flyxxthemoon Does this only happen when there's snow on the ground? If so, you have this issue:
[CURRENT ISSUE 64-bit] Walls/floors cut away to display snowy roads | EA Forums - 11185408
There's no fix, and the only workaround is to disable Advanced Rendering, which lowers the graphics quality in a significant way. Or, I guess, you could use cheats to set the snow level to zero. Or you could play at an angle where there are never any roads behind your sim's house.
