I found an error on the sheets that actually potentially ruined everything. It was a single letter I mis-typed, but as a result, the NDP's ratio total needed for vote calculation was actually being pulled from the PC Party; which is why the AFF was so high.
When I fix it
I end up with more errors however, 20.
The last time a projection went this disastrously for me was also the last time I tinkered with the sheets as much as I did (Quebec in 2012)
