Please disregard. An older version of Kelly's pack works great and the NVIDIA maps work great. I can't reproduce on all RTX packs, just the one so I don't think it is a Minecraft issue.
Sorry for the confusion.
Petition to re-open this issue!
Kelly's RTX resource pack was used for testing.
Steps to Reproduce:
Set your skin as a character creator skin
Join a world without a RTX texture pack
Skin shows up as expected
Quit and enable a RTX resource pack
Re-join world
Skin shows up as Steve
Quit and remove RTX resource pack
Re-join world
Skin shows up as character creator skin
Observed Results:{*}*
Adding a RTX resource pack makes all skins into Steve.
Expected Results:
Character creator skins function in a world with an RTX resource pack.
Can confirm this issue on dedicated server 1.14. An entire line of chests in a chunk are invisible but still have a hit box, breaking them drops the chest but not the contents. Item frames have their item disappear and cannot have an item added until replaced. Piston heads disappear and just have the base. Weirdly enough mob spawners also lose their spinning mob and stop working.
Is it confirmed that education edition features aren't supposed to work on BDS? I was hoping to use the fly-but-not-creative feature.
