I just added and Rev2381 Ascent, this one didn't crash when I dropped an item, and I added NCDB Rev657, acording to SVN they added 2368_world_map_checkpoint.sql and 2368_world_worldmap_info.sql to it, unfortunatly 2325_world_creature_names.sql wasn't included so there weren't any NPCs. But after I imported it they spawned and also, vendors were working without additional fixes. Water wasn't working until I imported 2074 series files, after that STV sea and river was working as water. Still waiting for zeppelin to check other areas, too lazy to switch to GM account :P.
So, to have NPCs and water working I imported these files to NCDB 657
Code:
2074world_creature_names_localized.sql
2074world_gameobject_names_localized.sql
2074world_itempages_localized.sql
2074world_items_localized.sql
2074world_npc_text_localized.sql
2074world_quests_localized.sql
1649world_banned_phrases.sql
2325_world_creature_names.sql
2368_character_guild_checkpoints.sql
I don't know if 1649world_banned_phrases.sql is needed for something specific, I just noticed that ascent reports it as missing, after I imported it that message dissapears.
*edit*
Brightwater Lake in Tirisfal Glades also works as it should.
