Unable To Active Crates, Doors, Or Lifts.

[SushiX0]

I noticed this across a few different missions and areas, sometimes during solo runs I am unable to open any green (active) storage containers, operable doors, or usable lifts like the one shown.

 

This one was from an Alert Raid on Aphrodite in Mercury. I have had this problem exclusively with Crovus missions but a few infestion missions have also given me this issue. So far it seems to be completely random on when the bug replicates itself, but it happens mainly on my Excalibur Warframe. (I dont think that has much to do with it though)

Doing fancy parkour can get the game recognizing you in midair when you're not. When I can't use X on things, I test my super jump skill because it costs very little energy and it doesn't work in mid-air. To fix this midair glitch, simply jump and land; without fanciness.

 

If this isn't your issue, I haven't a clue.

Like the above poster said, simply jumping has fixed this for me.  Goes along with the "Can't use this ability while in the air" thing.

Ok, next time I run into this problem I'll try it out. The "parkor" is so buggy for I normally dont use it except for the slide, well that and I am just bad at it.

I have had this as well, but im not hosting I wouldn't be able to open or use or activate anything or even pick items up, its not a big problem as for it only happens every know and then off host but I do have this same problem and nothing I do fixes it until I exit game
