Currently there is only one known bug, t17 4pc isn't implemented for DEMO.
The goal here is to find any inconsistencies between logs and simc other than those listed above. If you find anything you think is a bug, report it here: https://code.google.com/p/simulationcraft/issues/list
Anyone that wants to, go hit up the Killable Damage Dummy. It is important that you find one with that name, as some will attack you/your pets, and some aren't level 103. Record the full duration of the kill, and post your log here. All warlock specs are welcome, the more logs the better.
Alternatively, you can do 5+ minute tests on a dummy that doesn't die ( the killable ones can take 15+ minutes, very tedious). If you do this, please make sure you note this in your post so I can disable execute in simc.
PLEASE USE ADVANCED COMBAT LOG - "You'll want to turn on Advanced Logging which can be found by going into your main settings by hitting Escape. Select System and then Network. There should be an option that is unchecked called "Advanced Logging." Select this and then close the menu. " - Zagam
Warcraftlogs is preferable.

Download this addon and type /simc in game, it will create a text output that can be used in simc to replicate your character.
Please, be specific about what exactly you did in the test. Did you pot, were you using any glyphs. specific talents, etc.
