Oh i see ! Well it wasn't really a big deal to be honest :) it's just that since there was no mention for that i just assumed from the numbers that you had to be exact :p
and i also understand for the removing of resources, here again i got it wrong and assumed that the key let you dropped no matter where, i didn't put 2 and 2 together to do it inside a ressource field
And honestly if you just add mentions on these aspects so that they can't be confused you've fixed all there is cause like i said the game is pretty solid otherwise ^^
