Hi Shousaka, I didn't know if you spoke Spanish or English, so I'll write in English XD, well look, when I try to do an event from the last update (the event to fight against Lilim's Valkyries) I get this error on the 0.30
This happens because this is an anniversary event and was only available for a limited time, if you have a save before the anniversary you can load from there to play the new content of 0.30, if not you will have to restart your game
