Thanks for the feedback! Stations need their inputs satisfied before they start producing goods, ships and equipment that can be bought. Explaining stations needs to be in a tutorial/help message.
I will put on the todo list:
- balance shield recharge rates
- ammo HUD
And thanks for the bug reports as well, will fix 'em soon.
EDIT: fixed some issues https://mpt.itch.io/system-drift/devlog/67841/version-013
