Suffocating when going through nether portal.

When playing in Realms going through nether portal from nether to overworld, player suffocates while on loading screen/building terrain screen. Belongings can be found at coordinates 0,100 (x,y) after respawn. Issue only affects 1 nether portal in realm, but affects multiple players across multiple platforms. Bug is easily replicable, and only affects one direction (from nether to overworld)
