[1.6.1+Orcs 1.1.0]Tinker can't go Tinker's cave in AoA game

[starsapphire]

Bug:

Tinker class won't get access to Tinker's Cave on the worldmap in Age of Ascendancy campaign.

Step to reproduce:

Make a tinker class character, go out to see the worldmap.

This may be a side effect of the escort tinker cave fix in orcs 1.1.0
