My own Lot got corrupted while building it ?

So I can't seem to find anyone with the same problem, since yesterday i was building on a lot in Innisgreen (the tree one) and at some point it made my game freeze. I can't save it to the gallery or libary, nor can i access it in build mode, no cc used it's literally just a shell and some terrain. I can't explain to myself what the issue is, it get's stuck in diffrent save files, removing and turning off mods didn't change anything. So it seems like the lot got corrupted but literally like how, I am so frustrated cause i don't understand it and you can't repair the game with the ea issue. If anyone has any idea, it would be greatly appreciated.
