A 3rd limited time event showed up in my goals and I'm not 100%, but I'm pretty sure it was titled papa's new bag, which isn't supposed to start for a few days. Mission 1 was to defeat 1 rival which I did, and I received Black Powder Power. Looks like the old flintlocks with 235/195 a/d.
Then I went to attack again and the game hung up on me. It didn't even time out and tell me the player is too beat up, just sat there for several minutes, and when I went back in it was gone. Looks like someone flipped the switch too early! Anyone else see this? Get any further?
