According to some posts for older patches of Legion, I only have to export the charsections.db2 to sql and change the flag cells to 19 then import to db2 but it reverted back when I started the worldserver.exe. I look up the flags on DB/CharSections - wowdev but I still don't understand the flags apart from 1, 17, 19, I thought 33 would be the demon hunter flag since only night elves and blood elves have it and changed the flag to 19. The changes didn't reverse this time but neither has anything changed on the character customization screen so I tried 17 and 1 instead; 1 crashes the server and 17 does nothing.
What did I do wrong exactly?
[please tell me I don't need to patch the wow.exe... I barely know how to read the db2 tables]
