Moorgard has posted a list of Splitpaw Saga known issues / new features here. But just in case you're the anti-"click here" sort, check this out!

When the servers come back up (estimated to be around 11am Pacific), there will be two known issues with the current update that we wanted folks to be aware of:

* Some harvested gems can be sold to NPC vendors for cash. Nothing is selling for incredibly high amounts, but it's still not an intended change. This will be fixed tomorrow.
* In rare cases, we found that group members would not receive an update for defeating a quest target creature in a Splitpaw Saga zone. We have been unable to reproduce this bug, so if you experience it yourselves please post specific details to help us track it down.

I also wanted to point out a last-minute cool feature that our designers snuck into the Splitpaw Saga zones. In addition to scaling to your party's average level, most of the zones allow you to choose your level of difficulty. You have three choices:

* Normal (only the zone name is shown) - NPCs are scaled to your group's average level.
* Difficult - NPCs are scaled two levels higher than your average group level.
* Very Difficult - NPCs are scaled five levels higher than your average group level.

Fighting the tougher versions of the zones will increase both the XP you earn and the quality of the treasure. Now you can choose your own level of challenge!
