The Ressource Hideout costs a fair amount of gold and will hide parts of the players gold and elixir depending on the upgrade level of the hideout (e.g. 10% at level 1 and 50% at level 5 while upgrading the hideout is very expensive).
The hideout has lots of hitpoints (also depending on the upgrade level) and must be destroyed completely before the gold and elixir in it is exposed
What do you think?
