Why is 'npcspecialattks' in the newer PEQ daily dumps?
 

This file HERE ... removes the field .. and is never added back with any of the other SQLs.. is there a reason it still exists? I see a command in game can update the field... but other than that I don't see anything else that uses that field. The inconsistent fields in the database can really get annoying.. so just wonder if I need to Axe it from my database or will this field be getting used ?

Most likely reason:
Because PEQ is the test DB and it was implmented on PEQ incrementally before the final SQL was generated and it was left on accident.

Seconadry likely reason: some custom PEQ tools might have broke back then when it was changed and it was left in "short term" and forgotten about.

Also, originally the PEQ DB dumps were a manual process that cavedude had to go through to create. That process is now automated and minor differences that that manual process took out/ignored are now just auto dumped.
