Thanks so much for checking out the game and leaving me feedback!
I'm well aware that the inventory is whole problem. The code that I've been using for it is actually outdated, so I'll have to check out a different way to do it. It might end up being an actual inventory instead of an on-screen one. Or I might just take it out completely. It doesn't add much to the story.
For now, the best way to not encounter that is to close the game out and start from the beginning (skipping through stuff) and not going back for different choices in the same playthrough. Or loading a save.
