Build mode/game play crash

Help! I'm experiencing issues with Build Mode, where only one action can be performed before subsequent actions stop working. Then when I try to save or exit the game, it does not save so I have to force end it. I also do not have mods/cc installed. I have attached my dxdiag info.

It worked! I tested/played two default EA-made lots in the same save and buy/build mode were working. Then I switched to my own game (with CC lot, sorry for the confusion) and they buy/build mode worked perfectly! Is this the usual work-around or would this just be a temporary fix?

anmido  I honestly don't know whether this would be a temporary or permanent fix.  This issue seems to have multiple causes, and sometimes the only solution is deleting the lot in question.  I hope that's not the case for you though.

Let me know if you need further help.

Hi! I did this on my blank lot. Still only letting me do one action. Then the next just don't get applied. It disappears.

anmido​  Does this happen with different sims too?  Please try fresh ones you create for this purpose.  You can use one of the CAS defaults, but don't download anything from the Gallery.
