Re: [FIXED] Failed to Compute Cost Error Message with downsized Flat Round

@blooossom please try the following steps: 1) remove any mods/CC, 2) clear your cache, 3) repair the game via Origin, 4) start a new save, and 5) test the circular flat piece in the new save.  I'm advising this because it sounds like their may be corruption in your game, and taking the steps above should remove it.  If you still experience the issue after following these steps, please tag me by typing @BryonyRae

@blooossom actually, I think you are experiencing this issue.  I am merging your post into the thread.

I also am having this issue.  I could delete everything except this flat.  I have tried all things mentioned to remove it and none work.  I even took out the game entirely, cleaned up files and such on my pc and then reinstalled the game.  I kept my cc and mods out of game.  went back into game, and lot was exactly how I left it before I took out game. Taking out all games, stuff packs, and add ons did nothing.  It is my favorite lot to play on.  EA needs to come up with a solution quickly

In reply to my previous post;  I don't know if this will help anyone, but it did me.  I had decided since I couldn't play that lot I would play another--as I was getting ready to fire up the Sims, I went on a whim to the saves folder.  Even tho I had uninstalled and reinstalled my game, there was stuff in it.  I deleted it all out.  Then started up my game after I put my mods folder with cc and such back in.  My lot was as it should be with the start of new game.  Saved lot to my library, then bull dozed it and started building.  Have had no trouble since.  So mine is fixed at this moment.  Had to start new game of course, but my lot is fixed!!  Hopefully this will help someone else.

Has anyone found anything to fix this problem? I'm currently dealing with the same issue and do not know what else to do to fix this problem. 

I cannot delete this flat and if I try to bulldoze the lot it get stuck in a loading screen with the same error coming up behind it.

Same issue. I downloaded a lot from the gallery which had a room that gives me the same error and now I can't delete the room or place another lot from the gallery as it gives me the same error message. Really annoyed. The lot seems to have been removed from the gallery at least.

I had this error and got the same message, and then I could not rotate or delete it any more, Luckily I just went back to the moment I picked it up.
So if you are in the building mode, you can withdraw from this action. Well, but unfortunately you have to guess that there is a problem.

I think ive figured it out, place 'styled rooms' down over the lot and delete them all along with the other things it wont let you delete.

Having the same issue with the broken round floor. unfortunatly the 'styled room' drop didnt work for me.

any word on a fix for this yet?

Hey! I have been having the same issues.  I tried everything you listed and it still never works. My game will freeze after every time.
