The meta event ‘In Pursuit of Knowledge’ (the one in Dredgehaunt Cliffs that leads to Dredge Commissar) can get bugged (read: is bugged in every instance I enter) due to no events spawning at Fridgardr Lodge. Likewise Ogre Wars (a thread was created for this already) also tends to bug at a certain event.
Suggestion to solve this issue ((obviously) aside from ensuring that all events do not get bugged): Seeing how guesting has been completely useless since megaservers (you’ll still get send to the same map-ip if you’re guesting to another server) I’d suggest letting guesting send you to a map-instance with a difference IP (which hopefully has a different non-bugged event chain).
