Okay, I was just reading it wrong then.
That being said,
the unlocking of the gallery breaks things.
The menu windows themselves are a little wonky, so when you enter the gallery, you typically need to open one of the side menus to 'refresh' the gallery, or else when you try to click on the Unlock Skull button nothing happens. After doing a 'refresh', then you can click on the Unlock Skull and get the text about spending the resources to unlock.
When you do this, the game will trigger a series of Loading Error messages that interrupt the game.
Actually, after more testing, it's not that the unlocking itself triggers the Loading Errors. With my Act III save opening some of the side gallery menus, like Meredith or Succubus, will ALSO trigger the Loading Error problem. This is with the still locked gallery, showing only the scenes I'd already triggered.

However if I'm in a menu that opens fine with the mod installed, like Clawyn, there is a really good chance that unlocking the gallery will now cause that menu to trigger a Loading Error tied to a relevant image.

For the record, the gallery was a bit hit or miss before. Some of the scene wouldn't play, or they did weird things like swap the gender of the MC. But this specific problem with the image Loading Error was a behavior that the gallery wasn't exhibiting before I installed the mod. I even did yet another fresh install of the game, mod free, and loaded up my Act III save. Accessing the gallery side menus didn't cause the Loading Error either before or after I unlocked the gallery with the mod not installed.
Thanks for the quick responses. I'm not upset or anything, I'm just trying to help you nail down these bugs with as much accurate information as I can.
