Sub prefabs not spawning their children

Hello! I am doing a networked game and I'm using DunGen to generate procedural dungeons. I have run into an issue where when I spawn a dungeon on user connect, it will not spawn the child prefabs with it. I have recreated a similar setup where I spawn the exact same prefab on server start, but I do not encounter the same issue. If someone from Unity would like a copy of my project, I'd be more than willing to send it privately.

 

Does this only happen with the ImprovedPrefabs builds? We have not changed runtime behavior of Prefabs, so it sounds odd if you're experiencing changes in how your game runs, compared to other versions of Unity.

 

Yes only in the improved prefabs build, I added a sub-prefab under a parent one, and when instantiating it through DunGen, the sub prefabs fail to appear at all. I'd love to share some code but I can't isolate it to reproduce the issue, I'd have to send the entire project I think.
