Maybe this is supposed to be a feature request. Either way this is extremely annoying.
I have multiple NPCs in my game. They use PathfindingService to get around. I also made it so they walk through each other (but not fall through the floor) using PhysicsService collidable groups.
This happens every time and probably has always happened. It’s extremely annoying and as far as I’m aware is impossible to fix as a developer.
Here is a repro. The BoolValue in Workspace determines whether or not the test is using collision groups.
