This list will keep growing, I'm afraid. Here are some more:

First up, proof that the quest issue isn't because I'm on the same quest somewhere else or that I have too many quests:

Note that I'm on the tile and there is only one other quest that I'm on, which is NOT this one.

Another dumba$$ diplomacy response, note that I'm friendly with these guys AND more powerful:

Here's a screenshot of the issue I spoke of earlier. This goodie hut has sat here forever, despite the fact that it's right by MANY AI cities! WTF?!:

Last (for now), here is a CAPITAL CITY that I've just taken from Resoln, about 2.5 hours in to this particular game. Note how LITTLE they've built....

It appears this game has a long way to go.  I personally am on hiatus for a length of time which has yet to be determined.  I am waiting for bugs such as these and many more to be fixed in the coming months, hopefully.  I like the game but cannot ignore the bugs in it as they are distracting to my game play. 

The third bug in the main post is a typical problem of the fact that you are already on the quest that the quest mrker would spawn. Namely if you finish your current quests you will be able to get tht quest marker. I really think some flavor text should be placed when walking over these quests markers that you are already on

"Everyone here seems to be too busy to talk to, and you are rather busy with the quests you already have. Maybe you should come back after you finished a quest."

or

"You are currently on a quest. This would be too much if I stop here."

or

"This quest is already being done. Come back after you finished your other quest."

While I agree that there are things that need to be fixed, this is the most fun I've had with Elemental, warts and all. I believe the main issue - the single biggest issue, really - is how retarded the AI is. I'll take pictures next time, but I've seen goodie huts RIGHT BY AI CITIES and they won't even touch them for a few dozen turns. The pioneer spam is absurd, too. In that game, Pariden ALREADY HAD 7 CITIES to my 3 and the average 3-4. Why does it need 6 pioneers????????

WHY?!!!

Nope. Check my second post now.

Some glitches I encountered recently-

I was taming beasts. I would web everything and tame the enemy one by one, passing on most of my turns. However, partway through this process a glitch often occurred, where a beast I had tamed suddenly got infinite turns and nothing else was capable of acting.

I noticed that, if I tamed a beast with a full army, it would spawn as a separate group after the battle. The important thing here, is that it would still appear after the battle, even if it died in battle.

I had a city full of defenders. All the unit slots+an assasin demon from the sacrificial altar+statue guardian. This resulted in some of my defenders being spawned outside the city, in the void beyond space and time. They couldn't move, since they weren't in pathable space, but were just sitting in the corner of the map.

Is that confirmed? ^^

There's a bug, then, because it's not shown on my quest list, as you can see in the second post.
