It seems SOE changed some skill types after 1008. I will investigate this further when I have more time on Sunday, but at first glance I saw at least these changed

<= 1008
General: 13
Language: 14


>= 1096
General: 12
Language: 13

How are we gonna handle this?

Same way we handle any other data version that requires different handling. if(version <= 1008) do it the old way, else do it the new way.

Oh second read, I have no idea what you're talking about. Could be a couple of things, so I'll wait til you have more time to ask a thorough question

Data Version <= 1008
Adventure Tab:
Combat skill_type = 1
Avoidance skill_type = 3

Tradeskill Tab:
Craftsman skill_type = 8
Outfitter skill_type = 9
Scholar skill_type = 10

General Tab:
Harvesting skill_type = 6
General skill_type = 13
Language skill_type = 14

The rest of these do not show up in a tab.
skill_type 4 = Armor skills
skill_type 5 = Shields skills
skill_type 7 = Tradeskill?
skill_type 15 = Fighter skills?
skill_type 17 = Weapon skills
skill_type 18 = Tradeskill?
