I have only minor bugs as well, and mostly about visuals. And like you said, " I didn't even realize they were bugs". I usually think of them as bad game design until I can't stand it. Then I went to search for a bug report to confirm my suspicion. (Because if it's only in my game, it might be the mod issue which is more dangerous than the unmodded bug)
I think TS4 can't break the PC itself. But it can break the save file or the whole game folder even without a mod (from For Rent period). However, the recent pack probably edits some "events" mechanics for the new date system. Gameplay has become wrong lately in University events.
I usually buy a new Expansion Pack to get time-limited contents but then disable it until I can make sure that I know almost everything that can affect my save file. Watching YouTubers and forums for a month before playing yourself can save you from issues in case of a long-time main save.
thank you for the comforting words. I really want the new game! I would have hated not getting it. I hope this new patch fixes everything. I haven't seen anyone I follow on youtube even talking about all of the bugs yet, and they usually do. Well, good luck on y'all's end.
