Are you aware that currently the highest possible warehouse level is 685, making it impossible to reach the next upgrades in "City Facilities"? I have all other upgrades maxed out (Level 5 and all upgrades, everything in the lab and in the office)
Bug:
If someone thinks you are overpricing an item, you still get -1 of that item in the stock, but not a -1 in the overall number of items you have in stock leading to being able to order less. I have a total stock of 155 but even though I can't sell anything (0 in all categories), I have a total of 144 items (when looking in the statistics)
