[Invulnerable Lich]

My lich became invulnerable after it clipped through a wall while stabbing it.

Edit:
It spawned again so I decided to record for evidence.
It always becomes invulnerable after the first stab.

2nd edit:

It started taking damage again after a few minutes of hacking at it.

 

[Titania Razorfly Weapon Bug]

Can't switch back to Pixia anymore once Diwata is used.

[Warframe Revised: Railjack Revisited (Part 1): Update 27.4]

Can you make the map in the tactical screen stay in place?

I gets blocked by some UI and some points can't be used to teleport.

[POE: Mortus Pink pigment not dropping when killing kuaka/ashen kuaka]

I took the opportunity to start the research for that color since conservation for them is going to be added but they're not dropping any pigments at all, even with Ivara's prowl.

[Valkyr not doing damage to Nullifier Crewman]

This happened to me many times already.

 

I ran as Valkyr on a capture mission with the Nullifier Crewman as the target.

I popped his bubble then used Hysteria, I was not damaging the target at all so I had to cancel the skill.
