[I keep getting dropped into mission nodes I didn't click on.]

Experiencing the same a lot recently, choosing it from the icons at top right on the alerts section or whatever the mission is takes me to another mission. I've kinda find something about this(at least i think)  choosing the mission itself from the node where the mission is takes you to the right mission "mostly". Hope it helps a bit before DE fixes it ^^

[[BUG] Brilliant eidolon shard cannot be placed on shrine at PoE]

I was helping new players to capture their first eidolons, everything was normal till we captured the teralyst. We got the brilliant shards and went to the shrine and its where the bug occured one of the guys couldn't place his shard. He had the brilliant shard on his loot but he could not place it but also he could remove "our" shards from the shrine and place them back. His only option was "Remove Shard" while he had his own. Then we couldnt continue on capturing gantulyst and hydrolyst because of this.

[Progress loss when you switch between DX11-10]

I just had huge fps drops and loading issues(started after the event patch Operation: Buried Debts), like running low settings got 80-90 fps but it drops to 20-30 suddenly and  then goes back up a little and drops again. It is really annoying and then saw on internet that it may solve the problem if you switch to DX10 and just had to try. Did switched and waited for the update and after when i logged in my last 1 hour or so gameplay was gone like i mean i did eso and capped my focus and leveled up my kohmak (0-30) then it was unranked after i came back and needed to cap my focus again. Dont know if i lost anything else.
