When opening the '?' context sensitive help icon within the Cartography Table UI, the help page for Loom opens. It looks like Loom is the last help entry under Crafting, which may be why this entry is opening. There is no entry listed for Cartography Table at all under Crafting (or anywhere else in Help that I can see).

This may be a more generic problem with the new workstations (eg Grindstone) - I haven't checked those.

I searched the summaries of all 83 issues matching "Cartography Table" but did not see anything relating to the Helptext.
