I was doing some work on my rpg Shadows of the Tal'darim act 1, reviewing quest chains when I encountered an odd problem.
I wanted to re-sequence the quests so there were not so many optional quests. I wanted the quest chain to be more linear.
When played online, it still executes the quests in the old sequence that they were originally uploaded in. When played as a sample map offline, it executes the quests in the new corrected sequence. It's running quests that I deleted when I play it online, meanwhile other trigger changes are obviously working.
It's like blizzard need to defragment their bnet map database.
