Space Rangers 2 Reboot question

[Chuglug]

Hello,

I am playing SR2 Reboot on Gametap. I am really enjoying it. However, I hardly ever see thumbs for trading anymore. If I actually find one, then it is only a few units. Is there any way to fix this? Also, I can't figure out how to raise my ranger rating. What do I have to do to increase that?

thanks

To advance in ranger rating, you need to complete quests, defend or liberate star systems, destroy pirate and dominator ships.
