Wow vanilla map pins are broken

[BannZay]

HereBeDragons pins throws an exception when you tries to add a pin for class trainer.
Tested on wow vanilla (11505) with only following addons enabled: FieldGuide, BugSack, BugGrabber.

Using the addon along with other dependant on HereBeDragons addons like RXPGuides, makes blizzard map completely broken.

I really like the addon and fixed my version by upgrading HereBeDragons (from v16) to the latest(v29) and tested. Both v29 and v27 worked perfectly).

Buggrabber Exception
