This is not exactly a bug, more of a suggestion after playing DoD these past few weeks (not sure about EoE areas, didn't get to them yet and old TR I don't exactly remember).
The Omaynis is lacking a topic. You can only ask about it in Andothren, but in the city itself, no one will talk about it, even the governor. And it's not that small.
Another thing is the local area/economy thing. Some places have it, some don't, it feels kind of random: for example Menaan has it, but OE doesn't. Maybe get rid of it or leave it only for important settlements?
Just outside the western exit (near the enchanter), there are several different roads going somewhere, but there are no signs which one is leading to the next city.
I have decided to compile a running list of all the bizarrely dialogue free NPC's I find in DoD/EoE. Some of these may be involved in quests, but even so in vanilla you can generally still ask for generic rumors or trade info...
Mortenius Becca, no dialogue (made fix)
Garila Delvarrapal, no dialogue (made fix)
Senar, only one generic topic
Duchess Perulia Jandacia, doesn't have much to say but is probably a To Be Written case
Of the four doors to the Andothren Port Authority, three are elevated to be above ground level, going to balconies. They should all go to the second floor, or at least the same floor, but one goes to the third despite being level with the others outside. Screenshots with labels attached.
This mine, just a short trip along the road out of Firewatch, contains over 60 rubies (somewhat random due to use of raw ruby deposits that give a variable ammount). There's no owner attached, and no scripts to indicate a gotcha. At level 2, there were only easily defeated animals in the cave, including a mudcrab that I don't think belongs, and the only opposition was a scamp outside (which my unprepared mage easily defeated).
Noticed that the book Ius, Animal God appears to use a Dunmer Temple-related cover; it is not a dunmer cultural book and should probably receive a more basic western type texture.
