In Isobel's quest, Tournament of the Heart, during the Sword Hilt section, the mobs are invisible, though my pet was attacking them. I believe they are Fauns[?] though I have yet to see one.
Also Isobel has been disappearing - her quest / interaction marker is floating around, but she is not there. I keep having to log out and in again to reset the things.

brejo is missing for isobel quest.
isobel was following me all over the island despite her quest was not finished. teleporting to other zone dismissed her.

isobel left from fist shine, some riding, near castle navire talking in front of the entrance for knight's arena.

ember - same shrine, ride right on the big road(crossing bridge) until seeing tower. shrine near that tower even discovered stays undiscovered on compass. (saw here invisible flys - aoe works).

Edit: /bug with screenshots submitted (kind of, just saw one of screenshots is missing)

"Tower Full of Trouble" quest seems to be bugged. When I try to restore Huldressa, there's no way to interact. I've reloaded ui as well as restarted the game!

*EDIT* I also unsummoned Bastion to make sure he wasn't interfering, still same issue.

*EDIT 2*
After restarting the game for a second time, the issue seemed to resolve itself.

• Ember has two lines where she says "Hey, you" (one when summoned and one when starting dialogue with her) that are clearly intended as a friendly greeting (HEEEEY you!) but are vocalised as attention-getting (HEY! YOU!). Please please please give the voice actors proper context around the lines they're reading so they know how to deliver it! All of the voice actors I've heard in High Isle so far, definitely including Ember, have done an amazing job but without proper direction it becomes jarring after which what is the point? (still not as bad as the problem with Ezabi though. You absolutely should know what I'm talking about)
• Aurelia's voice actor pronounces "Veloise" kinda funny, not really a big deal but kinda funny to do with her lifelong best friend's last name
• Glitches in at least three of Isobel's houseguest dialogues
• Achievement "Isobel's Favor", prerequisite for the achievements "A Knight's Best Friend" and "Candies and Cutpurses", includes the task "Interact with Lyris Titanborn". Talking to Lyris repeatedly inside the Annoucement Hall in Understone Palace does not work - note that this is the main reliable place for a character that has completed most content to find her, save for maybe resorting to going through Icereach all the way past the first boss with an undersized group for Isobel to be present (if that one even works either)

yup, isobel just dont like me, after brejo and another one, she disappeared on the green barrier, left interactif (cat something) is bit hard to interact.

I first last night had the bug where I couldn't undo the lifestock. I logged out last night restarted the quest. Had to start from the beginning but it worked. Then after I got the tombe I got logged out and when I logged back in I wasback at the livestock part and now I have the same issue on the guar.
