2 characters online in the same place, one (desynced) sees a lock on the gate even though it has removed it, while the other character (not desynced) is not seeing it - also, the desynced character cannot add the lock to the gate, while the character that is not desynced can.
To make it more simple I recorded a video to show exactly what happens: https://www.youtube.com/watch?v=xoNKaccWONA
This is the 3:rd time this week that this has happened, so not a one-time thing.
