Some success and some fails.
Tried to figure out wher I might be able to replace the npcid with a different npc and keep the grid and all in place. I couldn't (haven't) found a "grid" in the db for it but there is a pathing in one of the tables.
Went into spawngroups found an entry for the SirensBane with the spawn group ID. I forget what lead me to all this but found the spawnentry(table) id for the npc was 13206. How is this important. Low and behold the npcid of the SirensBane. Figured this was where I could swap out the npcid for something else.. it works...it fails...
I'll explain....
It changes the npc of the boat (tried with Captains_Skiff) and it does work but for some wierd reason I yet don't understand, it was a human model
So from this point I thought ok maybe I need to play around with the body type, gender, or even the race... nope.
Oh and when ever I targeted it.. it made my "zone.exe" crash it also crashed randomly a few times while playing with it in the database.
Before and after I tried playing around with the npc_type.
This does bring me to my next logical thought... something to have to do with the coding probably in the "zone.exe" files which I had started looking at.
Besides tearing the whole boat system apart, which I figure I could do from the DB, and rebuilding it with some grid, way points, and spawning and making a npc for it, I figure there has got to be an easier way of doing this or at least one that doesn't mean I have to start from scratch.
Watch, I end up not able to figure this out and I do redo the boats and it turns out easier then effort I'm putting into tring to just find a replacement.
Oh and that viking ship (HAHA still don't know what to call it).. there is more to that. It keeps poping up while I'm editing different aspects of the npc_types of different ship/boat npcs. almost like it is a default. Like the human models for some of the npc settings depending on the npc and settings.
I would blame it on maybe having the "Expantions" variable set to "0" but tried some other race types from other expantions and most of them worked.
