Gallery Library copied lot won't download in new game, no error message

So now I've just had 3 lots I tried to save to my library give me the same message - error lot won't save to library. There's no code showing. Just to test, I tried putting a lot from Ondarian in my library. Worked as it should. Perhaps some of my game lots are old and glitched, good enough to keep playing on, but not to make copies of.

Thanks, yes, but I ended up just getting a new lot. This happened a second time on a lot I'd converted from university housing to residential. (I'm consolidating all my played sims in different games into one save).

One thing that does help out sometimes is how you go about placing the new lot.  I feel that I have better success with going into the lot from the map, bulldozing whatever is there then installing the lot from the Gallery/Library rather than just installing it at the map screen.  It also seems to go faster doing it that way.  

Hope this helps.

I have no mods or cc in my game. Am playing on a PC. The lot does not place at all - the unoccupied lot is still there.

Could you please provide the following information

• Are you using mods/cc in your game ? Please remove them and test without them if you do.
• What platform are you playing on (PC, Mac, Playstation, XBox). Please pick a thread tag for that.
• Does it not place at all or can you not load into the lot after placing it ?
