I just played a Despia-Altergeist-Deck (yeah, that’s a thing) against Altergeist-AI. At the very beginning of the first duel, I normal summon Aluber, get impermed, then an error dialog appears. Something like "Attempted to call nil value method ‘isCanBe…’ " (or so) with one “ok”-button. Sorry, I don’t remember exactly the error-message. I can still search out Branded Fusion. Then I click on ok on the error dialog. The game still continues as fine. But I shouldn’t have been abel to get the search. (I have seen similar dialogs a couple of times lately. However until now, I basicly ignored them, since until the game was still working fine. So was I simply closing them until now.)

Sorry, I don’t have a replay code. Also, I don’t know, if one can reproduce the bug.
Screenshot OR error code
I shouldn’t have been able to look at my deck, and especially not been able to get the search effect.
What OS are you using
I’m using Windows 10.
Yep, it seems to be reproducable. Rematch against Altergeist-AI, get impermed again at the very beginning, still my Altergeist-Marionetter-effect doen’t get nagated for some reason. Still the same error-message:
?: -1: attemped to call nil value (method ‘IsCanBeDisabledByEffect’)
I guess for some reason, my effects can not be negated, although I have not Protocol on the field yet.
Pretty sure this one’s a known bug
Yep, it seems to be this one here. I only have seen it against AI.
It says there, one should wait for the next local core update.
