Only way to restore the bottom buildings without mods is by creating a new save file, it sucks ☹️
@crinrict I just did this!!!!! IT WORKED! I thought my entire save was a goner (I've been using this same save for over 5 years), but after reading your suggestion on disabling the pack, saving without the pack, then re-enabling the pack, the stargaze lounge lot returned to its original glory! The stargaze lounge lot in city living bugged for me after wanting to place a renovated version of the lounge from the gallery. Thank you for suggesting this.
edit: also, after the lot came back after re-enabling the pack, I was able to drop in the renovated version i found on the gallery and it placed onto the lot with no issues.
