I have this. I don't know if this happens for other events in the game, becuase i just checked out the most recent ones, but i have this premature ending issue specifically with latest skylar events. For example, "Skylar RP. Events" scene ends after each chapter, and i would assume it shouldn't, because tho see all teh chapters i need to replay it like 6 times, but also "rescuing Skylar from cultists has nos electable chapters and it ends after Fiona cums, but if you replay it from the regular gallery, it doesn't do that.
P.S. Other than that, thanks, your mod is a godsend
Sorry for the late reply. I've just updated the mod to fix this issue.
For whoever is interested:
Before game version 0.9.2 (released somewhere in 2020) it didn't contain a gallery. The mod added a gallery.
This gallery was still in the mod, in case someone loaded an old version with the mod. But, that old codes could also cause some replays to end prematurely.
So I removed this gallery from the mod... I don't think anyone is really going to want to add a gallery to such an old version of the game anymore.
