Game progress not saving; exiting to manage worlds resetting progress made
EDIT: After playing a bit more I've zeroed in on the actual issue here: going to manage worlds, exiting to main menu, closing the game, etc. resets ALL progress made in that sitting. I attempted building from live mode by moving in a sim on the apartment I wanted to build. Then I spammed the motherlode cheat a few times to have enough money to actually by the decor. When I went to manage worlds after building, not only did all of my progress on the build reset but my sim's funds reset to before I used the motherlode cheats. Basically, nothing in my game is being saved.
Build mode is presenting a unique issue with not saving progress and causing game crashes. Whenever I enter free build mode on a lot from the map, in this case I'm attempting it on a San Myshuno apartment, any progress I make is not saved. However, when I enter build mode from live mode and build there using the owner sim's funds, then the progress is saved. After that point, if I enter free build mode and make progress, then it's preserved.
I tested this on an earlier save file where I went to the same plot I was attempting to build and I tried just deleting some items, including one of the windows, in free build mode, exiting, and then trying to reenter free build mode. Before entering build mode I saw that the window deletion was undone on the map preview, but the other items I deleted remained deleted. Then when I tried to reenter free build mode on that same lot, the game crashed. This was after I had deleted the localthumbcache, removed the mods folder entirely, and repaired the game ergo playing on a fully vanilla game. I play with a lot of cc so I was wondering if it was cc causing the issue, but seeing as this issue persists on a fully vanilla game, I believe this may be a bug with the new feature allowing us to remove and replace apartment windows.
I don't want to have to use this multi-step workaround that involves moving a new household into a lot before I can build on it. I want to be able to just build on a plot freely. If anyone knows a solution to this, please help. If this is a bug, I hope it's fixed soon.
