Due to how laser beams are implemented each active laser adds around 800 packets per second, sometimes more depending on the length.
With 20 lasers running at the same time the game is unable to keep up and starts teleporting players back or disconnecting (even on an integrated server).
How to reproduce:
Place multiple lasers and activate them
Open debug menu (F3)
Look for the "rx" value (Third row from the top on the left side)
