Even though I have already completed Brink's campaign, I can't seem to do anything else with the game now. (Due to my internet being horribad) So I decided to play SP with a new character, but I seem to notice something Day 6 of the Security campaign that got me frustrated....After I repaired the crane, I proceeded with fixing the other crane that gave us a new route so I can finish the mission quickly. It worked fine, and the AI was acting dumb enough already. So I die because of their negligence to cover my a** while hacking the objective and decided to use the new route so I can get there before X number of res. engineers kill my hackbox. When I was crossing the route, I noticed 2 teammates (AI) were stuck on it and could only move inside that makeshift bridge. I didn't care at the time because they were soldiers, not medics or other Ops, so I moved on. 3 deaths later, I come back to the route, which had been recently fixed after the res. blew up the crane controls, and I see the same 2 teammates, still stuck, but this time, they were accompanied by other 2 of my teammates....the 2 medics on my team were stuck now and couldn't move....just great. The mission ended, I lost. I had to watch the end cinematic dozen of times before I called it a day.....

Long story short, my teammates get stuck on the new route (the pipes being held by a crane). Is there any reason why this happens? And why only in this certain part of the map?
