2 Garrisons built before turn 9, 3 Commons Quarters (Grand Teahouse) built at turn 10.

On start of turn 11, Slaves not unlocked, but Fundamental Values (require 3 Commons Quarter) unlocked.

Attached is saved on end of turn 10. End the turn to see the bug.

(Materials Procurement is also not unlocked although Humanism is researched turns ago.)
