So this glitch happens with all CC removed? including any lurking in saved Sims, installation files as well as your entire download folder pulled out? I want to be sure you tried this CC free.
I have moved the entire downloads folder which only contained custom content of the smarterepcheck and nosimloaded although the glitch still appears in my game. However, I have noticed something interesting that occurs with the glitch which is when I custom price an item over 200 simoleons the glitch of the sales bar appears, which means I am not able to price items at any number above 200 for some odd reason. Therefore, when I custom price items on food (as I have been using food to test the glitch) under 200 simoleons the glitch does not appear and I can get customers to buy the items.
