Finding ore is extremely hard in the early game

You can't really restart the public servers. I wrote the original post thinking about how it takes hours of checking asteroids to find cobalt, for example. I'd like the game to be more bit-by-bit. Currently, if you don't do an eight hour rush your progress will most likely be lost because your base will be griefed overnight.

I can understand this to be a problem starting in space. I usually start on earthlike planets. You can search ressources on them without the need of oxygen bottles and less energy consumtion. I cannot say much about puplic servers in this regard. I do like building huge structures both on planets and in space so those servers with build limit arent really my thing. Only thing i really wished that ore sensors would have far increased scan range. I mean 150 meters range for a sensor build on a base. Even mods dont go above 300 meters or something.

The build limit isn't really the problem, you can gather a bunch of friends and build some big stuff. The problem is griefers. It is possible to abuse the spawn system in a way that allows griefers to find and destroy everything you have built. So you must rush to get a safe zone before your first disconnection or else it's likely that all you have built will be destroyed overnight. Hours are wasted finding materials in this critical stage.
