Just a List of Bugs I have found in the game.
1. Jolteon Evolution does not work, already mentioned.
2. Stoutland icon in stats is buggy, seems to revert to Herdier's when moving, and has no evo animation or send out animation.
3. Not sure if bug, but Porygon goes through evolution twice on level 51, just slightly odd if you ask me.
4. Arceus cannot be bought in store, it registers the selection but funds are not taken and Arceus is not given. Probably a simple fix.
5. In the Kanto Region, there is a ledge you can leap over and you will leap over, and onto a house with no way to get off besides teleporting, might want to block off that section of the ledge as a wall instead to keep people from getting stuck.
6. Phase through the ship on certain islands, not really bad but something of note. Mostly I believe in Snow-Port and one other place I'll add it on when I remember it or find it again.
7. Bug where if you send a pokemon out as a Follower they are invincible. Something that should probably be addressed so it isn't abused.
8. An Odd bug with the mart in the town where the Fire Gym is located, I walked inside and walked out in the main town just north of Unown Cave.
that is all I have for you for now, glad I could be of service.
