I understand if you haven't downed Turn 1 but downed Turn 2 you are locked out from 1.
While I think that is ridiculous,thats not my issue.

I have been trying to down Turn 2 all week since my static group didn't form this week.
I tried 3 different groups,I got turn 1 down but never 2. My free company asked me to go to Turn 4 with them. We did not down turn 4 but now I am locked out of Turn 2. Why?
How is that fair that I now miss out on a chance to get loot for the week because I wanted to attempt Turn 4 with my FC. I could understand if we downed turn 4 and I couldnt go backwards but like i said even that is ridiculous...

If you haven't finished Turn 1 or 2 but attempted 4 without downing it,you should NOT be locked out of 1 and 2.
Now I lose a chance to get gear from turn 2.
