I try to write a guide to your game.
Edit: Thanks to a friend I got over the 3rd puzzle of the Thelamore Ruins and all other puzzles I couldn't do.
Edit: The I got other ore later.
2. I can't convert 10 Modest Miscellanous to 5 Fascinating Miscellanous. It says it isn't enough.
Edit: This bug persists, it was only possible for a short time around the Main Story part in Setra.
Also when you upgrade the shops the last time you don't only lose the 25 needed Outstanding Miscellaneous but 200...
3. (new): When you have fished an UR fish before you got he Fish List in Easthaven, you cannot finish this side quest, because he doesn't recognise my Thelassian Swallower.
Some smaller bugs: One mining spot for Coal Ore in the Faluh Mines main area will vanish if you destroy the pillars in the wrong order (the ones to the NW). Neverending fishing in Thelamore and Crying Forest.
Many passabilty glitches (ignore them as players) and grammar errors, but it is comprehensible.
There are even some positive bugs (at least for the player), but with so many bugs I won't report them.
