the upgrade system has a big flaw, it doesn't only fail it also degrades WTF!!
are you trying to get ppl mad and ragequit...
plz remove the degrading instead make it like more expensiver or harder but plz no degrading..
at some of the npc of quest they spawn alot of minotaurs and they back up so i cant hit him and after the timer runs 0 i lose wasting like 30 min.... plz change the timer bc it kinda sucks
