Hello!
Thank you for the bug report.
I currently have a running theory, but wanted to ask before I start coming up with a testing methodology.
When you had this occur, were you able to select your materials, and/or the monster to summon, and then it crashed? Or did it crash immediately when you activated the card which would allow the summon? The A.I Love Fusion & the A.I’s Ritual?
Asking for clarification.
Thank you!
