Running latest PetTracker from Curse.

The following error pops up now and then, but especially when changing spec.

20x ...ddOns/PetTracker/addons/main/features/objectives.lua:54: bad argument #1 to 'ipairs' (table expected, got nil)

I get this same error, tho my GetContent call is on line 49, same file (I haven't looked in the file).

Getting the same error:
