v 0.46 took 90% of my money (about $12e+15) and the save issue it's not solved so I had to start a new game and leave my main frozen in a backup.
On my new game I needed some aluminium and went to the trade board LTA just to see other player posting 100al for $1,025,509,719,000,000 (about $1e+15) and it was sold seconds after.
Also the price for 250al on the Black Makrket went form $300k to $9M. The Export prices are really low and the 75% tax makes a gift of everything you try to sell, and waiting for someone to buy your resources on the LTA can take hours and there's always gonna be someone just selling cheaper to sell it fast making the game harder for new colonies.
Maybe the LTA/LTB should work different, perhaps putting the colonies in tiers based on their GDP or tech level to see different offers/requests on the market so players who still have $1e+42 doesn't affect players with $30M.
I know it said "hard" but having no source for al and this insane prices, makes the game impossible to continue. Having uranium and aluminium harvesters is pointless in the LIS asteroid.
