Posi, I'd like to point that I just now (like 1 hour ago) attempted a timed Lost mission in the 25-29 lvl range (which I wasn't told was timed by the contact btw), which apparently involved securing a portal.
I was warned beforehand that that mission was bugged (mission failed within 5 mins, apparently because of mobs attacking the portal I was to protect), but knowing cape/war wall had been fixed I thought it would be fine.
It wasn't. So if you could please address that particular mission fixing as you did cape mish et al, that would be nice
PS: I didn't even get a "mission complete" text so that I could check the mission name. All I know is that it was a Lost mission which involved portal corp and had a 2h timer on it (which I thought was odd).
