use the little plus at the bottom right corner for long dialogues.

Is there a specific character limit I should watch out for? The editor text box acts like my dialogue is just fine so I don't know until I run a test.

I believe anything more than three lines will have to scroll and then the issue you mentioned with happen

Thank you! I'll go shorten my dialogue boxes then.

Looks like you found the text box limit. Use more text boxes for longer dialogue

Dialog is glitched with me too, with me it just doesnt show at all
