Do you have the latest public version? There's a Clear Images command in the wrench icon in the phone.
If you want to help us out, hop on the discord and send a screenshot of the Leslie bug
I have actually has some similar weird glitches with older scenes like the movie night stuff or making dinner for Les. Like for the dinner one, when you can change the angle it won't actually load some of them. Like I hit change angle and it's just the empty couch, hit it again nothing, 3rd time it's 1 of the 3 angles. But it doesn't always happen so I didn't bring it up in my own post. I'm playing on Android btw, and dunno if some line of code causes some scenes to just not load properly now. Kinda like back when Brandy's sex scene dropped and her body didn't load into the scene but the belly marking did so it was just floating on the bed xD
