Wurm problem
The worm always spawns. Always.
However, since the mercenary event bugs out (as you say: the mercs stop appearing sometimes), we sometimes have to wait a while before the boss appears. I think the longest I’ve been on a map between merc start and wurm spawn is just under an hour.
So wait it out or change maps (there are plenty for the moment), while ANet investigates the 13,187 reports (including at least a dozen forum posts) about this issue.
Definitely a bug, definitely should be fixed. At least there’s a work-around (even if it’s ugly & inconvenient).
