I ran Mirra's Sleepless Night's post U17 Update.
A few items to report.
My war forged Hireling Blast nearly died while taking damage beside a closed door. There were Wights and Zombies on the other side (first path to the left at the room prior to the Iron Golems).
The named Specter passed through the closed door at the end fight and attacked us even though the door was closed.
Ghouls still have a gelatinous blocky graphics bug surrounding their body.
The floor of the end fight room was covered in green graphical blocks rendering it difficult to see.
The floor of the first room with a chest was covered in green graphical blocks making it difficult to see.
The dungeon is very, very dark. I have difficulty seeing chest, levers and even monsters. Adjustments to Gamma and Contrast seem to have no effect. The difficulty to see greatly diminished my play experience. If this were my first experience with DDO I'm not sure I would give it a second look.
