[2020] Warframe stops existing (disappears) after summoning Necramech during bounties.

I will dig into this immediately. This kind of report is extremely helpful!  I've been seeing several posts about "disappearing frame",  but this is the first time I've seen a full session *leading up to* the problem, and it's full of relevant facts like: it can happen solo, it's not limited to the Isolation Vaults, and it doesn't require any specific frame or ability usage. Thank you!

Doesn't require any specific frame, doesn't require the iso vaults, doesn't even require a bounty or combat of any kind. As near as I can tell it's related to moving very far distances from your mech's previous location without hitting spoilers mode in between.  Worked up a set of steps for our bug-slaying ninjas, hope to get this fixed soon. 👍
