Hey everyone. Thanks for being patient with me as I worked on the mod. The Ep17 mod has been released and the OP has been updated as well. Feel free to give it a try.
TL;DR, Cheeky added some more code to an old file which was replaced by the mod. This was causing the newer game to crash with the older mod. Not as big of an issue as I previously thought it to be.
Also, the game now comes pre-packed with a Gallery of its own. But, if I'm being honest, I prefer the one that I built - looks cleaner from my perspective. That being said, I still have the gallery that I built packed into the mod, so if you copy over all files from the mod then the native gallery would get replaced, but you'll also be able to free up some extra space (check the Changelog for more details).
And finally, I've added a gallery unlocker in the gallery. Try it out - I'm not a very aesthetically oriented person - so sorry for the buttons looking ghastly
