Shulker boxes disappear from inventory in survival when switching from survival to creative.
==What I expected== Nothing, I just went to cr to design a shop.
==What actually happened== When I went back to sv, my shulker box had disappeared from my inventory.
==Did you see any sort of error message?== nope
==How can we recreate this bug?== The only way I’ve observed it happening is having the shulker box in your main hand, but it could be possible for other hands to work too.
