"Only enable items researched" It doesn't work.

I turn this setting on to keep myself from buying something I haven't researched, but nothing changes. I can buy myself any End-Game item and easily skip the stage, bypassing almost all technology. Even for example, I can build a spaceship while staying in the Iron Age.

It is important to add that this is corrected by completely restarting the game. Sometimes not the first time.

This is not working on MP at all either, even after both client and server restart. It feels like this value should default to true regardless.
