I recently upgraded my reserve hangar 2 to level 2. I had 2 spots from level 1 and I bought the first additional slot with greens. When I upgraded I only received one extra spot, and the 5th place now costs 20 greens again. I already made this purchase, and I find it strange that now I'm asked to spend money again on something I already bought a long time ago. I opened a ticket to GI and got this answer: "Hi! When you upgrade the building, the number of closed slots will be increased. So, you will have additional slots but need to open them with banknotes. It is the game feature." Anyone else experience this issue? I'm pretty sure I should have gotten 2 extra spots instead of one.
