Can't get out of Alva incursion in group play

Hello,

bug n# 3 683 647 692 :

I can't get out of incursions in party play.
We are a group of two, both with mercenaries. My mate (owner of the map) can get out of the incursion, but not me, I have either to disconnect or wait for the timer to end (where I get normally kicked).

It happened in two different maps (Jungle valley T16,5), so it was not an isolated thing.

Thanks for your help.
