Just finished a strike when I was on my way to the tower. When I get there, nothing but the tower itself actually loaded. No NPCs, no players, nothing. The other person in my fireteam said the same thing was happening and we couldn't even see each other.
I tried a "misadventure" to see if respawning would fix it but to no avail.
I went back to orbit and re-entered the tower and everything seemed fine again.
I'm wondering if anyone else has had this happen?
