This is has been an issue for a very long time (before Fortuna) and apparently it's happening with ability nullifying enemies in Fortuna update now There is an enemy that locks all your abilities. Sometimes he appears to lock all other 3 except the active one. Abiltiies seem to return when he is killed. Either way, when I am in "operator form" during this phase of abilities being locked, my Warframe's abilities are permenently locked out even after the enemy's death and the only way to fix
