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.

 

And how might I proceed about doing any of that when the map will not load for any players in the forge?
