Softlock after host migration during fissure interception

[doomsdayforte]

I recently went through one round of Rhea/Saturn with getting all of the reactant, but the host left after the first round at the extract/continue screen.  After the host migration, my Warframe was frozen in place and I couldn't do anything and I believe the new host was in the same state.  No enemies spawned either and even pressing 5 only shifted the camera around but I was then trapped in an invisible frozen Operator mode too.  The new host eventually aborted and I was booted from the mission entirely. 

 

I have had this happen once before on Xini I believe (at least that map layout) too.  I have F6 pictures of both instances if those are necessary.
