Quests, where do I go?`

Zoom out to the cloth moth. There should be a yellow house icon. That is where you need to take the woman to.

I have same problem coming back. I got a dragon egg and should get a dragon at the end. I stepped on the yellow icon and nothing happened. 

I've faced a couple quests where it shows no location of where to go. One was where I was to escort a nobleman to an estate, but it was nowhere to be found on the map.

I've found that many of the quests are broken.  Just this afternoon for example I recovered Sarog's Egg and returned it to the ruins only to get the updated text that says that I have completeted it and Sarog has joined me but, you guessed it, no Sarog.  (Prior to 1.06 I have successfully gotten Sarog to join)

Another quest was to find "the location inscribed on the wall" which when I found said location the text merely said "the location mentioned on the wall", I went to it and it disappeared without any completion, update or anything else.  The thing that irritates me the most is that it seems like you can only have two active quests at one time and I seem to always "bug out" with the lvl 3 ruins.  I have played 15-20 games now and every single one of them has been broken (quest-wise) with those damned ruins; I can still collect caravans, libraries, abandoned loot, etc... but I cannot receive new quests after this point.

I dont know, I've been playing (too many) hours ever since the release, but I think I hit my breaking point today with the game being "unfinished".  I am putting it on the shelf until the large update we are supposed to be getting in September.  And its not just the quests, it's the lack of AI, the inanity of doing most of your tasks, and the straw that broke the camels back came today when my first born daughter (to a standard adventurer wife) came out with 356 essence!  I dont know, I went off on a tangent here, but the morel of the story is QUESTS ARE BROKEN...everything is broken....
