I started a quick game to test this mod and encountered some things I didn't like very quickly.
First, half of the systems in my starting constellation has only 1 planet, even though the mod is supposed to make that rarer (and 1 planet systems were rare for me before I installed this mod). I'm pretty sure I specifically set all settings to "normal", but maybe not. Is there some setting that could have caused it, so I could check?

Then I encountered minor factions. The first one I encountered already had 25 relation points with me, and it said that it'll gain 25 more next turn (and cost of praise was around 2000 influence), but it never did. I have no idea what caused it, is it supposed to be like that with some factions?

P.S. Did I understand correctly that probes are now more expensive, have a 3 turn cooldown and there's now only 1 probe per module? What's the reason for nerfing probes so dramatically?
