As you can see from the image, on the tier 2 version, after about opening for us approximately 10 times (out of accidental hits on it) the gate then decides it no longer wants to open for us. Which leaves us with the unfortunate problem of no escape. We tried many many different solutions for this, including spending approximately 35 energy on revival explosions to set off the explosives) only to have no avail which is why I am left with posting this. I hope this bug is remedied quickly, because I would like to fully enjoy the OCH missions on tier 2!
This happened to one of my partys on T3, only it wouldn't open to begin with. We filed a bug report and had a GM kill them so we could proceed.
