Ah! So this is what you mean. I know exactly what is going on. It isn't a bug at all. So the cursor shows up when there is more text for that character/narrator. It's like a, "continue reading" indicator. I could look into removing it altogether but at the moment it is working as intended.
Oh! That explains it. Haha I guess I was expecting it to be more like how in RPG Maker it's there at the end of every piece of dialogue. Sorry for the confusion.
No worries, even seemingly little things like that are things worth mentioning. If other people find this confusing I'll remove the cursor altogether. I really appreciate your prompt response on this so I can continue to improve Hiro's Ascension swiftly!
Unfortunately, that would end up being more work than it's worth. I'd have to make custom graphics for that which is just not worth it. Would be easier to remove altogether.
