Alright so I've come across an insanely infuriating glitch that I managed to pin point but can't figure out a solution to the problem or what exactly is causing it.
I dunno if anyone else is having this issue but right after learning Nagasaki in Canada, the last three Chinpokomon (Beibersaurus, Mouse-Tik and Shoe) all disappear from the map and aren't able to be collected.
I creeped my way through Canada and after every major quest point I saved the game and went back to check the sewers for Beibersaurus he remained there until I learned Nagasaki... right after learning the final fart he was gone.
Is any one else having this issue and can anyone figure out a solution to remedy this? It's really annoying me and it's a game breaking bug that needs to be patched.
