Hey, sorry this is still happening - we've had a go at cleaning this up previously but we weren't aware there were multiple instances of the issue occuring.
I've had another go today and we look to have identified what's causing it. To avoid it until fixed, when your sword finishes (the interface closes) make sure to progress through any dialog properly, rather than clicking out of it.
No update on when this fix could come out to you guys unfortunately, hope it's not too frustrating! :(
