I feel like the Xp reduction for Asteroids is much too agressive, yea sure they're infinite and pretty much literally drop more ammo, but i feel like there's an issue when i can simply spare a single biter base to get an infinite source of >LV20 turrets requiring mere minutes and a stack or two of ammo each, but in space my ships can sometimes make multiple trips between planets before a new core will hit even just LV1...
if that's how you want it balanced I'd appreciate at least having a setting to adjust this rather than having to up base xp scaling to comedic levels if i want my space platforms to ever reach levels where i can even feel the fact there's leveled turrets on there.
It'd also help if you at least mentioned this mechanic somewhere other than the changelog where you introduced it as i was confused why my turrets weren't leveling for a while before figuring it out
