Can or cannot redo a scenario?

[fusei]

So I find myself unable to redo on the same difficulty an already completed scenario (pressing the button "start" but nothing is happenning).

 

Now, I don't know if it's intended (in which case it'd suck bad) or not. Been reading some one year old posts saying it is a known bug but I would have figured that it would be fixed by now.

 

Any help appreciated, cheers.

I’ve never had a problem replaying a scenario (and frequently do for Daily Challenges).

 

Is this a problem with a particular scenario or all of them?
