fall through floor why porting also all I can see is inside my body

why I fall through the floor when i use the portal I fall through the portal and foundation and then all i can see is the inside of my body. all I can do is kill myself. this causes me to lose all my stuff.

It’s a known issue, that hopefully gets fixed when 1.3 goes live. Building teleporters on ceilings with rooms below and not using other players teleporters for now. See also: Public Beta Client - Patch 1.3.0
