Navigation of the mission tree when you get a pop-up is the most troublesome part of this mod's experience. I found that if I went into the mission .yml files and added a tag for each '_title:0' it made finding the appropriate missions far, far easier. E.g. for HulazKrakazol, I changed the title to this:

" krakazol_block_passage_title:0 "Block the Passage (HK)"'

Or alternatively you could use a prefix.

" krakazol_block_passage_title:0 "HK: Block the Passage"'
