How come when I’m in a game for a while ppl start to glitch out and run in place it’s weird?

This is usually lag caused either by the player's connection, or your own connection. Strangely enough, if the person freezing or lagging, changes skins, this fixes the problem sometimes, but only if it's their own connection that's lagging.

Yes skins does help but not for long. No it isn’t not something to do with the players connection. IT wasn’t a glitch in the game which they have now fixed
