I (and a friend) got stuck on this mission with the system not recognizing Epoh tags (although counting them strangely enough).
We can't start the timer and are stuck with the mission now, since we can not even drop it.
We were on a team of 5, with teh other 3 able to finish the mission properly.
Sorry for any mistakes, english isn't my primary language.
