I sent Ymira to gather support, but she never returns to me. On my companion mission report, it says expected back in approximating in 0 days for a really long time now.
Same Problem here.
Currently 7 (!!) of my companions are "returning in 0 days" since one in-game week or so.
One cause might be, that at first I recruited every companion there is and then send all of those I don't really want in my party to gather support/Intel. When the first ones returned they got told that there is no more room for them in my party ("12/20, no place for you Jeremus!" ). This way I kept them within reach but without negative effects on party morale. This went on for a few days till they could be send to gather support, because the first 2 support-missions were completed. However that doesn't mean the first 2 support gatherers had returned, just that they were listed as "returning in 0 days".
Dunno, maybe this screwed something up...
Does anybody have similar problems or even a solution?
Oh my god... the companions in this game are bugged as hell!
I heard of other ways they can go away and never return.
And it also happened to me, but it happened when my companions got imprisoned in dungeons. After I conquer the castle and go to set them free they just disappear forever from the game. Here, take a look at my thread about it: http://forums.taleworlds.com/index.php/topic,105561.0.html Many others have encountered the same bug!
