[BUG: Fortuna/Octavia warframe claiming outposts (defense) - wont update]

Hi,

I haven't managed to claim an outpost now 8 consecutive attempts with Octavia frame while using stealth + mallet. After timer runs out i get stuck in "Defend the comms system" and it effectivelyseems to stop all progress, treath level doesn't go up even if i'm picking up a new bounty or trying to claim another outpost. Am I missing something or is this a bug?
