[Major/Fatal bugs V12]

I have put this in the wrong places before and I'm sorry but now I am just going to leave this here and leave it to be fixed.
My issue is every wild encounter gives me this script error, I've updated my game and hoped that would fix it but it didn't.

My game constently gives me this error whenever I encounter a pokemon near Goldenleaf town. 

Edit: I can Also only assume it will happen in others places too I have just yet to check and I also used to have no issue running Into pokemon only a bit earlier in my play session.

What makes you decide to remove or add  certain event pokemon from the game? Examples being Shadow Tympole and Shadow Toxicroak.
