(it was from the relic that pops up a window with a choice of 3 potions, that you can instantly play during a battle, i think every 25 cards played)

i had that relic for a few combats and it seemed to work fine, but then it started crashing with the same error when it would trigger, and i had to use the console to remove the relic before the 25th card, and was able to complete a battle, and then i added the relic back again, but now it seems to keep crashing so i had to remove it but am not sure what causes it)

maybe it uses the map seed to queue up a list of potions, and 1 of them that it wants to keep trying to make as the next potion in the list is conflicting or something but am not sure).

Thanks for the report. I've pushed out a fix that should prevent the crash.

cool thanks :)
