I make a game in where I am the only Civ, I research up to the Gathering tech and receive only a single worker even though it promises two. Researching religions do not grant great prophets despite that option being enabled. And other techs do not give great people when they should. I had started with v27 and this bug did not occur until i had loaded a worldbuilder save (from same version), after that no amount of reinstalling resolved it. I left hoping it to be resolved. Half a year goes by I try again with v33 and find it persists.
