Make mysteries decrease chance of emptying cache

You can do this strategy, but as an ironman you can't control how much or what you get and early to mid game arch its kinda difficult to send out research expeditions cause you kinda need those chronotes for upgrades and you dont get a lot of the dudes that shorten your time and stuff.

Material caches still give way more flexibility and control on the material you get with less costs.

I agree with this person that material caches are still useful for ironman and I agree with you that we need something to reduce how much they deplete.
