I have:
Basic aircraft limit: 50 planes
Construction: 10
Foreign air base: 20
7 aircraft carriers: should be 35 but only lets me buy 25
Total: Should be 115 but won't let me buy planes past 105
Am I missing something?
(I just sold 2 aircraft carriers and am down to 5 now, in case someone notices. But I could never buy past 105 when I had 7 carriers)
