Telluria Bugs

City of Brannon:
Ulinta is marked "Male".  Her First Aid skill doesn't work with new container-type bodies.  Neither does Tercill's later on.
The trainers at the Guildhall have some bits of convo that clearly belong at Skytos.  And they take ALL the character's money!
Should have some explanation of why Marcel isn't there (until you find Rave).
Hunting Bird's "No exp" trigger doesn't work quite right, Dog may be the same.  I've written it some brains that improve with experience, if you like?
Hunting Bird is a Bird, you fool, not a Plant!

Derth:
Several convo topics check for a factoid called "BaronDerthQuest" instead of "MetUlinta".  And those don't work anyway.  Guard Captain may not check at all.
Baron's story (cutscenes) is a bit garbled.
Wave Woman's cutscene should be illustrated and isn't.
Wave Women's jetty doesn't work right - boat joins other PCs instead of replacing them.  Other jetties OK.
Coriolis Ring doesn't use its description, and the Single Jet option does nothing.
Eischen's trance trigger should be Pre-TurnCycle, not Pre-Turn.  Even when I altered the timing, I'm not sure it worked right.
I think the Advisor cast Thought Loss on himself at one point.
Eischen fights you when you've finished with those two!
Fog in the North quest isn't removed on completion.
Give Rave's stats more colour?  And he should be Locked in Tome.
Old Marcel's instructions for rescuing Juchen are rather involved.  Maybe a journal entry?
The Free Juchen quest doesn't go when you've done it.
If you meet Marcel after rescuing Juchen, he tells you to go to Trestle, which is in fact empty.

Junction: 
Cleric says you've no money, when you have.
Werewolves in dunes are a problem if, like my party, you didn't buy any silver weapons in Brannon and are now outlaws and can't go back.  Maybe move silversmith to Derth?

Mounds, etc: 
Lord Falinor's diary has to be used on an item to be read.
"Coffins" could work more smoothly.  
Also some of those faulty Dune Hounds (Dune Buggy Hounds? ;-) ) that have "ActionPoints + 10" instead of "- 10".  Same in the Dunes at Junction (which are another quest that hangs around when completed).

Dragon Flies: 
"Gazebo" encounter isn't anywhere.  Its trigger should be once-only.
Much harder than most others, especially final fight.
Path doesn't open if you kill Lost Woman in some tricky way, like with a Vorpal Axe.
"Leave" encounter doesn't fire, anyway - trigger timing should be Post-EnterEncounter.

General:  
Many missing creature, item and tileset pics as usual.  It's the underscores.  You can usually find them by using "Find" in Creator to search "Data files" for "_".  
Some outdoor maps (e.g. Derth and many other towns) are too sparse, tiresome to explore.  Better to cut them a bit smaller.  
Sketch-map of Telluria would be nice as overview, to work out where Southern Spine and so on are.  Maybe no labels, don't make it too easy.
