NoMethodError???

[RhadamanthusBeanstalk]

Please tell me if I'm putting this in the wrong place, this is my first post here. I downloaded the game once I heard it'd been completed, and it's been smooth sailing so far! (The passwords certainly help, as I am far from a competitive battler and have no idea what I'm doing 99% of the time lmao)

Also, please forgive me if this post is a cluttered mess due to all the hidden text, I'm trying to go by the "better safe than sorry" rule when it comes to spoilers.

 

Chronologically, I'm 4 badges in. However, I have encountered an issue.

When I got to 3F of Pyrous Mountain

after

Azurine Island

, it somehow triggered a dialogue with Victoria. As soon as the dialogue ended, I got a pop-up with this error message:

I would greatly appreciate any help on the matter. I'm not the most tech savvy, so I don't want to accidentally break something trying to fix the issue myself.
