Victus and Wrex have disappeared

Tis a bug. Wrex and Victus will not leave the ship till the genophage mission has been completed. Looks like you'll have to load a earlier save, unfortunately. Hope you're the paranoid sort who saves often!

I completed the meeting and normally would enter the War Room to speak with Wrex & Victus separately to get their mission requests (Note, they all now active in the Galaxy Map). However I diverted to the Prothean DLC first and upon my return to Normandy they have Vanished as well. I went to speak with Eve in Med BAY and Wrex enters to engage with Mordin as usual. Back to War Room, still gone. Did the Grunt Scout Recovery, spoke to Wrex in War Room, he leaves and I can now talk to Victus.

So, NOT immediately entering the War Room seems to trigger the Bug , bot for me is was minor, missing some Side Dialog but back on track
