The Brainy'AK tree is completely screwed in the viewer, previously it worked ok.
This might be because one of their techs (along with the Peacekeepers) was duplicated. Namely PilgrimageTech is there THREE separate times:

Those blocks start on lines 11541, 12018, and 12721 on the BRAINY'AK tech tree, FWIW. The sole difference between the one on line 12721 and on the first two, is that the one on 12721 doesn't have the Capstone feature.
FWIW, on the Peacekeeper tree the duplicate techs are on lines 11598, 12034, and 12737, and follow the same pattern of two capstones with one without.
