it is confusing because in the old versions the hero revive depend on his level
but in TK when my hero was lvl 9 first time i revive him it cost me low resources and 1:20:00 hour
in the second time it took him 5 hours to revive and much resources than the first time
i ask my friend in the chat and he said it depend on the population
but i didn't find that make sense
can any one help me please !!
