Help! Prefab Broke Map

I placed a prefab in my map created by someone else. It is a relatively small building but it increased my light budget by like 50%. My object budget was about 80% after placement.
I deleted the prefab and saved. I then realized the building was still there after being deleted. So I tried to delete it again but couldn’t select it. I then realized I couldn’t select any objects or place any new objects. When placing new objects they just wont appear, no message or anything.

So I thought I would just quit and reload the map. But, now I am unable to spawn in Forge on any team and just remain dead. Custom games by default on my map produce the same result on all teams. I was able to get the map to load in a custom game by disabling all placed weapons and vehicles but this is not an option for the forge that I can see.

I ran the map in forge mode and opened it up to public. Another player joined and they also were unable to spawn.

I believe what is happening is not all objects are loading due to the glitched prefab. And disabling placed weapons and vehicles allows the spawn points to load.

I have a previous save that works but doesn’t have all the detail and I have spent a lot of time on the map since then.

Does anyone have any other suggestions to fix this?

Edit: The view the the map gives me when I’m stuck not being able to spawn shows some weird geometry. It looks almost like a bunch of huge shadow planes floating in the air. I do not see those when I disable vehicles and weapons and play in a custom game.

Why don’t all maps just have a non deletable spawn point at the maps ceiling that is only used for the forge? Or forge spawn just use a random point if no other spawns are detected? Or even a button you can press that randomly spawns you. This seems like something that is very easy to fix but yet many people seem to have suffered from similar spawning issues.
