I just ran into this bug. I had some instances of a prefab in the scene and I went edit the base prefab. I wanted to add an EID of a child entity to the schema of the base parent of the prefab. when i did that it didn’t add that change to the instances of the prefab already in the scene. I had to delete all instances and then re add them for that to be set. Here is a screen shot of what I mean. Tt is the child entity eid in the schema of the pillar one prefab entity. It happened to all 4 of the prefabs i had to update. not sure if it only applies to eid or other schema value changes.
Thanks for posting this, I’ll share it with the team.
