Verification builds and Platforms: Minecraft - Release_2027367 Minecraft.Windows_1.11.23.0_x64_UAP.Release_Test

Summary:
Mobs summoned with /summon or created via a transformation in a behavior file will randomly fail to spawn. We have witnessed this in multiple variations, anything from a one-off in our command blocks, to having ~1 in 7 fail via commands (see image below), to transformations failing. I'm struggling to consistently reproduce this bug. The world I've sent in to Quinn has reproduced it under the steps below 4 times in a row for me, so hopefully the same happens for you.

Impact:

This project sequence breaks in numerous spots if key entities don't appear. This project will not release until this bug is fixed.

Repro Steps:

1. Get the world related to this bug from Quinn on slack.
2. Open the world
3. /summon noxcrew:fw.scientist_alan_upsidedown
4. /bounds
5. Punch the hitbox of the entity

Observed Results:
The entity disappears! When the entity takes damage, it is supposed to transform into a remodeled/re-textured panda.

Expected Results:
The entity should change into a properly stood up version of itself.
