"System Error" when placing lot

nautcosmo  Ok, then.  You can't change the venue anywhere other than on a lot.  Usually, there is a popup that you get when the venue on the lot you're trying to install is different than the venue of the lot you're trying to place the lot on that asks you to pick the venue before the game will place the lot.  Residential rentals seem to be different than other venues though and you don't get that popup.  

So, here is something else you can try.  Try to place the build on another lot.  If the same thing happens, then the lot has glitched more than likely.  It does happen from time to time, even for a player's own lots.  I've had it happen twice.  Idk why it happens, just that it does.  If it does place, you'll know it's not the lot in your Library and something to do with the lot you were trying to place it on.  If it places, then you can go back to the original lot, bulldoze, change the venue, and try to place another lot of a different venue type.  If that places, the bulldoze, and try again with the original lot.  Sometimes that will clear a lot of whatever caused the earlier error.  

If none of that works, start a new game and see if you can place the lot there.  If it doesn't place there either, then the lot is probably glitched and you'll have to build it again if you don't have an earlier version of it in your Library.

Hope this helps.
