[Kuva Ayanga broken in Archwing]

Agreed.

[Kuva Ayanga blast damage removed since hotfix]

Same issue.

[Void Fissure, Reward screen bug, can't extract]

I have this bug 3 times today.  All 3 times only 3/4 players were at the extraction point when the extraction timer ran out.  The reward screen showed and "H name name" with a white square icon in the center while the Reward timer counted down to zero.  Then we were able to choose a reward as normal but the game stayed on the reward screen until I force closed the game. (No loot from the mission after restarting the game) Or a host migration occurred would show the reward screen and extract as normal. (Loot gained as normal)

[Capture container mission inside tall caves]

I also run the bounties solo and missions that require you to be in a cave to complete are never enjoyable even assuming that I can complete them. This is true for Orb Vallis and the Plains.

 

[Excavation - power cells mobs do not spawn]

I am encountering the same problem.

[Ivara Sleep arrows only sorta effective vs Plains creatures.]

I can confirm this bug. The sleep arrow did work correctly on the plains animals previously the last time I had this riven challenge.

[Invulnerable Reinforcement Beacons]

I can confirm this.  Killing the enemy that deployed the reinforcement beacon is the other way to remove the invulnerability.

[Suggestion; Umbral Reactor]

I am suggesting a way to reduce the drain of the Umbral Mods on Warframes with a new item the "Umbral Reactor."  Umbral Reactor would work similar to the Orokin Reactor in upgrading and being applied the same way.

The Umbral Reactor would reduce the drain of each Umbral mod by 3 points. Equiping all three Umbral mods would reduce the drain a total of 9 points.

Three maxed Umbral mods total drain of 48 now reduced to 39.

I realize this does introduce some power creep, for me a player who has an orokin reactor, an exilus adapter, all non Umbral slots polarized [and extra forma to unforma 2 D slots] on a warframe like Inaros I still have a empty slot on my frame.

 

[Cave Bounties are VERY Broken]

I am having the same bug with the Cache hunting stage.  3rd time now.

[Cave Cache finding bounty mission is Bugged.]

I have the same problem.  I can only ever find 1 of the 3 caches in the Southeast most cave.

 

[Mastery test 21 broken - timed exterminate has no enemies]

I am having the same bug.  No enemies and no orbs in the practice test.

[Mastery Rank 21 Test Bugged]

I am having the same bug.  No enemies and no orbs.

[Door wont open after Stalker]

I am very tired of failing missions because the door wont open after the Shadow Stalker appears and is successfully killed.  On a recent Meso survival mission all the enemies could walk thru the door towards us but we could not get out even after multiple host changes.  There needs to be a /unstuck like command for doors.
