when you go into a house and close the door fast enough behind you while moving out, your character will stay inside the house and you can move along invisible for all other player while the character is stuck inside the house. You can hide your character inside a house you would never expect someone to go in and move along the map invisible for everyone else!!
Pls fix this as soon as possible
Our internet connection is very good and it does not always happen, but we noticed this on a lot of experimental servers. We are from germany and we noticed this on german, uk and us servers
