Minor map bugs found

Hi, 

I've just been doing some testing on this map for use in a future wipe and found a couple of bugs you might not be aware of, nothing that makes the map unusable but if you do any updates in future it would be nice to fix these too:

1. There are invisible blockages outside the keycard doors in both of the custom monuments with puzzles that prevent you from walking smoothly past those doors
2. With part of the Cobalt Bunker being underwater, killing NPCs there causes their bodies to float up to the surface rather than fall to the floor, in one case we found their loot bag had floated up through the monument  to the surface
3. At both the Radiation Research Camp and the Cobalt Bunker, the NPCs can see and shoot through the walls

For the known bugs on the Giant Excavator and the respawning of those blueprint fragments, you suggested using plugins to solve them, did you have any particular plugins in mind or was it more a suggestion that it's possible to create plugins to solve them?  (just out of curiosity, why did you turn the excavator arm anyway?)

Otherwise the map looks great, really nice job!

Thanks.
