For now, make sure you do your bio con before your Darmos, if you want 2 raids.
Good luck.

Known about this for a while now, not reported it, purely because i believe it is by design & if it isn't, then imo it needs to be.

The task that causes the issue requires just 3 successful raids, if you can re-raid after using the Darmos ability it effectively allows you to use 2 arti's on the base to get 2/3 on that Legion Mission, so this is why i believe it is by design.

I had exactly same experience. Guessing the glitch stems from using base related items. We had someone bunny up first THEN do damos and it worked fine. I did what Bonny did, and got same results.

I didn't really need the bio con to get my legion mission. If only 1 darmos per base, that is more than fine with me.
But missing out on Bio Con on a level 7 base, sucks. I want 2 numnum crystals
Won't make this mistake again, just posting so ppl will avoid my mistake.
