It can happen with all images it seems from my second playthrough and they can also change during the playthrough. they even persist after reloading a save once it has them. Loading an older very early save that never had them works though, till it starts again after some time.
In second playthrough had it with the end yoga scene, was later replaced by same thing with a scene from the x-mas special at table, later with a scene at end of victoria handjob scene and later a scene with Ostara.
Edit: not sure this was intended either and just not implemented in new engine, but also skills seem useless now or at least upgrading is not shown on skill screen. You can hang up the cam in bathroom after buying but says after you have no cam on computer and when you buy anal lube and after check deliveries you get a chocolate bar, but never the lube. Even if already have the chocolate bar. Also not seen an option yet to train magical ability as was in old version, that may be intended though.
