Sooo....
After fiddling around with the previous version (0.4.0) that I still had on my drive and the current one (0.4.1) I'm left a bit confused in one regard on the technical side specifically and I am not sure on how to describe it as I'm not technically versed enough, but I'll try regardless:
(information: This was only tested with bots supplied via mods, might have to test fully vanilla to make sure.)
When the game selects the visual for the scene when training a bots sex skill, it is noticeably slower in doing so, to the point where visual issues crop up. The following issues I was able to notice: The old visual still appearing on screen when selecting the "repeat" option, said old visual being then replaced by a newly selected visual that is put in the previous spot in the previous aspect ratio, then re-fitting the aspect ratio for that visual, the game selecting the same visual twice on a single screen.
These issues did not exist on version 0.4.0 of the game when using the exact same list of mods (I even just tested this to make sure). Once I noticed this behaviour, I did what one would call a "clean installation" with the base game and same mods - that I downloaded fresh for this purpose only - and those issues still persisted.
I'm not sure if there's an issue with my machine that is hampering the visual selection or if something changed in the code, but it's noticeable and jarring enough that it hampers my enjoyment playing the current version.
