Rsearch Bug?

[Katznelson]

Researching all cost related upgrades does not correctly reduce Tier 3 research options. I could not research a 120 cost option with just 100 even after every other research is complete.

Or I could be mistaken with this but I had this problem recently.

Reclaim genes to get 10 points. Do it twice with 100 points
