Hall of Mirrors bug

[light_in_dark]

So basically this bug occurs on  Icefields of Riddah  (grendel chassis mission)

symptoms:

1) mirage creates single projection without duration limits

projection appears on mirage location, and stays there till the end of mission

projection doesn't shoot, and draw enemy aggro

2) mirage can't use abilities

3) inability to use melee

posible fix: run to the edge of map (teleport back)

PS. does same happen on other grendel missions? someone need to check

This also occurs on the survival mission

This issue is still present. It already got reported in full detail in February 2020 https://forums.warframe.com/topic/1169777-mirage-bug-grendel-missions/ 
Is this a try forcing the players to not be able to do them missions solo?

Just experienced this bug myself. This really needs to be addressed directly. It's clearly not meant to work this way.
adding one of my own screenshots. It's evidently been months that this problem has persisted, can we at least get this acknowledged, if not fixed?
