I've noticed that when a miner with the profer iff n id mines, it gets the bonus, but when a cargo hauler of of my my buddies is next to me, he gets the cargo much slower and lower...
it supposed to be like this?
if you choose him ...then starting to mine....Due to Lag / losss...it can happen.
if you press Ctr+T or simply choose an object like sun...you will get ores normally faster.
cuz if your friend got a Loss in connection...just part of data you send to him will be recived to his side...which means Lower and Slower ore /mining.
