Welp, finally got some downtime available to check out the update, and it was going mostly well but I encountered a Game-breaking bug, not sure what exactly is causing it. What I did was the following:
After trying out the new bandits event at night in the alleys, I wanted to test more combat with a full party, so I went to the Brigand Camp since I had a couple of quests there anyway. My team is the basic MC+Aqua+Darkness+Megumin, everyone using the alternate skins (The blue one for Darkness, this might be relevant). Seems like it's going all well and dandy until I use Bolster Ranks with Darkness and the enemies attack. An array of seemingly infinite exception errors then ensue (ignore button doesn't help and rollback just sends me back to the map selection), apparently the engine unable to find some assets for what I can only guess is some special effect or something.
Darkness is equipped with the Thorns armor, Bolster Ranks is using the self-marking ability, resistance to de buffs and the Riposte buff. I have confirmed that other characters can be safely attacked without errors, but when Darkness is marked she taunts, and when she receives the next attack my guess is that the game doesn't expect her to apply Thorns and Riposte at the same time that she's Marked, or the issue might lie on the attack from a bandit causing a special debuff that doesn't mesh well with the buffs previously applied.
I'd like to spend some time testing further for a more accurate assessment, but unfortunately I don't have the time for such luxury right now, so I wanted to report what I found so far. I'm playing on the latest free version on Android by the way. If you tell me how to do it, I could reproduce the bug and send you the error log, although as I said there are seemingly infinite of them, as when I keep pressing "ignore", new ones keep replacing it (actually, it seems to be the same log but varying some numbers which I guess are code addresses)
