You really should nerf the blackjack battle against the succubus during vampire route
It sort of is. If you completed it during the hunter route first, you can skip it entirely in the vampire route.
And if we start the vampire route after each new update with the provided save game i assume that is not the case, right?
Right. The save files assume you started the vampire route as soon as it becomes available in the hunter route.
If you want to customize your save more in depth or skip certain parts, I offer a dev room with cheats as one of the perks on my patreon.
