A baby zombie materialized inside a fence post in a room with high levels of light. I could not hit the baby zombie because it was embedded by the fence post. I had to break the post to release it and kill it. However, it should never have spawned because the light is too bright for it to have normally spawned.

Had a couple of other instances like this where zombies and a creeper spawned in very bright conditions. This was happening on the old version of the console and was fixed. Its happening again in the Bedrock version. Makes it chancy to walk away from the console in fear of something materializing when it shouldn't. No room, no matter how bright, is safe.
