Player will let go of the 3D models and it will show and error on the hosts screen. (The players 3D model being glitched can be seen on the others screen.) The error will only show for a few minutes. This glitch was found on a flat world that was Creative, with Experimental mode turned on. 

This might be a 1 time glitch because of switch MCPE being the most buggy version i've play of bedrock.
