Bugs I've encountered while working on my project

[Derxwna Kapsyla]

I blame the fact that I was rushed in updating to v12.2 (I had to use my parents computer to update, so I couldn't double check everything I updated as I updated it, since my main workstation is broken) and I was being nagged to get off the computer the entire time while updating so I kinda powerhoused through it to get them off my back. In hindsight, that was probably a horrible decision, because now I have bugs that I have no clue whats the issue with them.
This one comes up when I access the Mystery Gift option on the New Game/Continue/Options menu:

---------------------------
Touhoumon Faith & Prayer Version 1.8
---------------------------

This next bug came from when I attempted to evolve something. I gave it a glance, and I assume it has something to do with the music that was playing:

---------------------------

I'd really appreciate if someone could help me understand how to fix this

Not sure about the first one, but the second looks like it's trying to play a sound file X, where X is a BGM, SE, etc, but the value of X hasn't been set. So it'd be calling for ".wav" for instance, which won't work. You need to have X set before you call the music.
