Yesterday when i was on the assault course i found that it I kill teh dummy to start and when the door opens i can restart (k) where teh door is, and when i restart the door is still open because my body is keeping it open. I can then run through the course with all of the dummies gone which i can easily get a cobalt rank. But then when teh door is still open and i kill the dummy again i can start the timer and then kill myself and it would freeze on that time. So essentially i got one of the best times: 0.0 seconds with a 1,500 xp score.
Assault Course BUG

At least I was able to reproduce it like that. 
- start the Assaut Course
- kill the red dummy in order to start the race
- notice the timer is about to start / has started
- stand right in the middle of the door that just opened
- restart by pressing ‘k’
- notice the door is still open and no timer appears
- progress through the course
- notice when crossing the finish line the time equals the time shown by the timer at step 5

Assuming ‘blocking the door’ (either with your dead body or an ammo pack) does not cause the actual issue, here is another way to reproduce the issue:
- start the Assault Course
- kill the red dummy in order to start the race
- notice the timer has started
- run through the door that just opened
- press ‘k’ in order to restart
- repeat 2. and 3.
- press ‘k’ without (!) going through the door (in case you pass the door and press ‘k’ the course will restart properly)
This is reproducible always and only after restarting the course at least once. In case 4. is not executed the timer will restart.
