I had nearly everything fully upgraded with a dire shortage of wood and I couldn't figure out why until a mission involving hitting trees came up. Talk about "can't see the trees for the wood"...
Finally completed on harder after over 200 days. When I started I had 40 soldiers, with 2 days left I had 6 alive and they went on strike, somehow on the last day I got the 'defeat' ending but it gave me the badge :o
I'm not complaining, it took me 7 hours to get this lol
