Raids still bug out or crash/disconnect post patch, causing you to lose progress you didn't save because you don't expect a $60 purchase to perform so poorly you need to save that often.
I've lost 18 shiny pokemon to this issue alone, that said, it is by far the easiest game to shiny hunt in due to new mechanics other pokemon games don't have.
Frames are really, really bad. Like, if you enter a body of water and try to move around more than two overworld spawns your gonna see those pixels hit max overdrive.
If your scanning reviews trying to decide to pick this installment up late to pass the time waiting for the next Pokemon Legends Z-A, don't.
