[My head it be missing!!]

I had this many times. For me it happened mostly on public games where im NOT the host while using/changing out of operator. Very often i see Tigris weapon in a state of eternal reload  (broken in half :D ). Check your ping, a lot of wonky stuff happens when connection is bad.

[The achievements of my account within the game, should be synchronized with those of Steam]

This is weird. Im mr21, i have all normal achievements in Warframe but on steam only like 50% of them. 

For example i have on steam  a "Cheater of Death" (revive 1000 allies) but "We Shape Our Tools" (put a mod in to a weapon) is still grey.

I feel like a newb. :D

[How many people use the Melee Counterattacks ?]

Damn, i forgot something like that even existed.

[Question about Clan Dojos]

That would be really nice. But i think that we need more capacity in rooms to truly make use of new dojo content. I had to abandon few projects because i could put just 5 decorations in half of the dojo rooms.The only new thing in dojos are event rewards - and obstacle course with parkour 2.0 is ancient and useless now.

I wish we could make our own types of obstacle courses in that room. I wish for some Dojo Patch adding new rooms and new decorations too.

[Can't get Dragon Keys BPs]

I hope they release hotfix for this asap.
