No quest greeting found error for multiple NPCs

Description: No quest greeting found for multiple NPCs in a new install.

Current behaviour:

On a fresh build and install of TDB, I am experiencing an error where after completing a quest for an NPC (who offers a follow up quest), the second quest appears to be auto-accepted (it is shown in the quest log).

In the worldserver I see the following message: Guid: GUID Full: 0x20000400002FE5000000000000000028 Type: Creature Entry: 49044 Low: 40 - No quest greeting found. Server.log attached.

The quest works correctly, but the quest greeting is not shown.

Expected behaviour: Quest greeting should be shown, allowing quest to be accepted / declined.

Steps to reproduce the problem:

1. Create Undead new character
2. Accept "Fresh from the grave"
3. Walk to hand in NPC
4. Right click to hand-in
5. Quest greeting is not shown, new quest is added to log

Operating system: Windows 10 x64

Reproduce the flow with a new Undead character using the listed quest steps, then inspect the worldserver output and attached server.log for the missing greeting. Trace the NPC's quest hand-in and follow-up quest behavior; done means the greeting appears and the player can accept or decline the new quest.
