It is the regular daily - not Alchemy. Has been a quest I've done since the DLC came out just suddenly stopped working.
Put a support ticket in so waiting response.
The quests that Razgurug gives out are all "collect 6 special things from X resource nodes and 3 other special things from some other location". The bugged one is the quest for alchemy reagent nodes (there's one for alchemy solvents instead of provisioning, which makes sense), sorry for not being specific.
The other kind of bug it can be is where it doesn't reset at 1 AM Eastern, but where it resets 24 hours after you completed it. But either way it's not consistent with the other 5 resource dailies.
picked up 3 dailies today instead of 4. Missed one of the slug town dailies (from that orc guy). Apparently something is messed up with the cwc dlc. Even morrowind dailies behave differently.
