Guess I got a few bugs to report, In regards to the arsenal card it seems if you play it after the AERA card while the deck is empty it ends up adding 4-5 upgrades to the deck instead of just 1.
Also the new game + generated by losing to the Giantess results in a event flag contaminated file. You start the new game plus only to be instantly ambushed by the giantess again. Although I got an hp score and deck suitable for taking her down there's an issue with the cruel destiny card she plants on you. It says it should rob you of 50 height among other things upon entering your hand. Problem is it blew away a few hundred thousand height even in the new game+ making it basically an effective game over in one hit that's delayed till after the fight is won due to the resulting negative height.
Also the buff the restaurant cook grants disappears if you move between locations. Same thing with the 4 themed boxes sold in the bazaar.
Also when fighting Valeria although up to 1k can be wagered only near 100 actually gets applied to her when she loses.
