The game would not let me play till I had updated to v1.68 so update I did, the following are some problems (or changes)I have noticed since.
Durnan and some NPC's in the yawning portal are red ( I assume the ones with new cloaks) though I can still sleep near them, this means of course that you can not converse with Durnan. Also the gem shop on level 3 is sometimes red sometimes blue!!! Thinking it was just a minor glitch I let the server reset a couple of times and even tried a old character, same problem!
Also
Drow leaders ring quest on level 2, cloak in chest comes up as 1935343616 as a description.
Nessat the drow (loki quest) no longer drops a sword (level 2)
No Xanther thieves guild protecting the wagon full of gems (level 3 south)
THEN .. I did the 72mb patch2 update as Ziroc requested and the Durnan/NPC "red" issue at least has gone away. [img]graemlins/thumbsup.gif[/img] The others still have to be rechecked. Anyhow I strongly suggest you update now
