During your third hang-out with Kovle, the receptionist's sprite persists on-screen even after you finish your dialogue with him and are supposed to talk to Kovle next. I think this isn't supposed to happen because the receptionist isn't involved in any way that requires his sprite to stay on-screen during you and Kovle's conversation, right? (Except when he was called by the MC to pop up behind the counter, but that certainly doesn't count since it was just a dialogue thing, and even so, his sprite shouldn't have been placed in that spot)
The sprite bug has been addressed in our development builds for some time now. It should be fixed in a few days when the new version is coming out. The saving bug though, that's more interesting.
Does it happen every time you save, or just sometimes? Can you describe the steps you're taking when it happens, and maybe where you are in the story when that happens?
