We all get annoyed by the bridge who lags and makes all the mice fall through... But what do the admins do about it? Nothing! It's such an old glitch that everyone gets used to it, but pls fix it!!!!

Usually laggy bride happens because of your ping or ( I forgot other reason but it causes lag) and too many mice in one room

It's a problem at one of the lowest levels of the game's mechanics. There is no feasible solution to it.
Either your ping is too high or the sync's ping is too high.
