Crash when using Blueprint to copy BITES THE DUST

[lazkmet]

I was doing a run with the following jokers, my game crashed right at the moment BITES THE DUST triggered.

Mr. Bones (Died on last hand to complete the current Boss Blind)
Word Whammer
Burnt Joker
Blueprint
BITES THE DUST (a plain Ace of Hearts was my last destroyed card)

Last hand was A A Q 9 3 of mixed suits

Blueprint was set up to copy BITES THE DUST, which was marked as Compatible in the UI. I expected both jokers to trigger, giving me 6 Aces of Hearts in total. What happened instead was that Blueprint triggered, giving me three Aces of Hearts, then the game crashed with the following crash report:

Oops! The game crashed:
functions/common_events.lua:2390: attempt to index local 'other' (a nil value)

(Edit: I thought Word Whammer also failed to trigger, but it turns out I had just sold my Splash - oops)

I have also encountered this same problem on this same version of the mod (1.0.0). Particularly, Blueprint trying to replicate BITES THE DUST. Interestingly, I too was set to produce Aces of Hearts (glass ones), and like the original poster, Blueprint made its three, then the game crashed.

Worth noting: I restarted the game and continued the run and tried again, and this time it crashed before Blueprint could make its copies. From this, I have to imagine the crux of the problem is that BITES THE DUST triggering automatically clears out the variable of the last destroyed card as soon as its finished creating the copies, in some way. So when its the actual card's turn, and not the Blueprint's, the value for what to create is missing, but it still tries to, because it partially remembers that its supposed to.

Your assumption is mostly correct. There's a partial fix here 4b0dea4 but there's another issue I wasn't able to investigate, so it's not merged yet.
