Weather, and NPC titles/lastname

[Drawde]

I've a couple of questions about the weather and NPC title features in EQEmu.

Firstly, weather - AFAIK the "weather" flag in the zone table needs to be set to 1 for rain, 2 for snow, and 0 for
none. However, it is set to 1 for all zones, and I've never seen it rain.
Looking at the 0.5.3DR3 code, the weather code appears to be complete, however. Is it broken in the current version, or
am I doing something wrong?

Secondly, the "lastname" flag in npc_types, I assume this is used for NPC titles such as "Warrior Guildmaster", "Spell Merchant", "Banker", etc.
However, it doesn't seem to have any effect - whatever you put here, the NPC has no title, other tha : n shopkeepers and bankers which have
an automatically-generated one ("EQEmu Shopkeeper", etc.)
