Glitch Mission 'Belgian Problem', upper tower missing?

[{FITH}™ Sammitch {FA}]

This is ~not~ to do with the Brute on the ball, which is pretty much the only other problem people seem to have on this mission.

After I free Oleg and get in the elevator I materialize above an already-destroyed tower along with a handful of NPCs that fall to their deaths. As seen in the screens below:

I've re-tried the mission from the beginning several times, as well as restarting the game and then doing the mission again, but this still happens.

I've also noticed some other weird things happening like the STAG barricades being all over the place despite not being that far into the story, and the bridges for the zombie thing all being up.

Any idea how I can fix this?

Well,have you tried co-oping the mission?
