My game crashes every time I encounter a pokemon in the Terajuma Safari Zone or start a battle with one of the Vileplume in said Safari Zone. This is the bug report (for when I encounter a pokemon): Could someone help me out with how to fix this issue?

That's probably it then. A bit of a shame, but oh well. thanks

well that's the problem, when I tried to use a heart scale at the move tutor I couldn't teach it roost, it didn't come up in the list of available moves

I tried to learn my mantine roost through the move relearner, but it isn't in the list of available moves. I checked serebii and it does say that mantine learns roost through level up (and through tm but that's besides the point) so I'm wondering whether or not this is a bug. Could someone tell me if this is normal?
