32767=2^15-1. Adding 1, we get 1 in the most significant bit, which will be interpreted as a minus for 16-bit signed numbers.
And I naively thought that 20-30 months is too long!
But I couldn't find another way to complete this map quickly. I need to bring a hero with amazing stats and thousands of units of level 6-7. And I only have a couple of cities that produce a few units of lower levels every week.
In my opinion, this is the most twisted map.
