Suggestion: Fix bugged events
My guess is that the fix for these events is not as easy as one might think. It may not be a simple matter of fixing event X, then moving on to fix event Y, and then event Z.
The bugged events all seem to be escort events. Izzy bugs out during the escort to Mel and crash survivors bug out during the escort to Meddler’s (both Cursed Shore). Malchor bugs out during the escort to Dwayna (Malchor’s Leap). Dobbs bugs out during the escort through the Rankor Ruins (Timberline Falls). Fire Elemental pre bugs out during the golem escort (Metrica). The meta event chain for the Branded Devourer Queen bugs out during the escort of Sentinel Whiptail or one of the later escort events in the chain (Iron Marches). Offhand, I can’t think of a buggy event in any zone that isn’t an escort event that stalls out or fails to start, and most (maybe all) of them have been buggy since the original beta.
This suggests to me that there is some very deep, fundamental flaw in something that is common to all escort events. The amount of work to find and fix such a fundamental flaw may be enormous, striking at the very heart of the code controlling dynamic events. The fix might amount to tearing down the entire game and rebuilding part of the foundation, which would present the risk of introducing new bugs that would be just as pervasive as the escort bug. The cure could be worse than the disease.
