This is a thread dealing with the issue started in Morrowind Spellswap.
"Say, I had made a request the other day in trying to make all the "well" references in Morroblivion point to the COBL well - see post here"
A lot of the posts in Morrowind Spellswap pertain to this issue. It would be sweet if we could move them to this thread.
I'll just start posting on this thread, knowing that anything referenced 'above' is from the Morrowind Spellswap thread. :D

"What do you think iceburg333
"What do you think iceburg333 - can we add the text to the mesh filenames for those wells? Or is it better to ask Maskar to add support in BPN innately in his next version? You may want to head over to tesnexus on Maskar's page in case you want to correspond with him (I don't want anything to be lost in translation).
PS: It seems we need not even have the COBL scipt attached to the wells, just have to rename the mesh (though does that create further complications, such as wells not showing in game due to missing mesh?). But it seems we need not have COBL as the master. Not sure if BPN needs to be a master either."
Okay, so I commented on the comments page an asked him if he could update the master.
This would be by far the easiest thing for us. Then we could trash the patch (or make a new one that just puts new wells everywhere). If we have to we can update the nif files, but that means we'd have to provide additional download rescourse files and we'd have to delete and replace all of the morrowind wells. The third option is to figure out which script he is using to find the nif files and update that ourselves, but hopefully Maskar will just update the master. Then we'ed just need to add some more wells to cities, which would be a cinch.
