Band Together Achievement does not give credit

I joined several public groups after 1.0.6 came out and never got credit for the new Band Together achievement that was added during that patch today.

At least it did not in Domination Cruel mode even after the patch.

I got credit later by banding in Nemesis Normal mode. May be a specific to Normal?

For me, it did not work in Normal league Merciless difficulty, but it did on Normal league Cruel difficulty.

Didn't work in Standard Merciless, worked in Standard Normal.

I have issues with unlocking this achiev, too.
For me, doesn't work in Merciless in Domination league.
I'll try to join parties in other difficulties, see if that helps.

GGG might still want to look into this bug, though, as I suppose it should unlock the achiev regardless of the League or difficulty.

It seems to work in Standard (merciless), Domination (merciless) did not work on many tires but Standard at the first try without even joining the same area.

Looks like the achievement decided to just ignore the Domination league, haha!

I can't complete this achievement no matter which difficulty or act i play. :/

didn't work in domination (any difficulty).

worked in standard - normal.

I couldn't get it to work on any zone in Nemesis, but it worked on Standard - Normal A1.
