ACR Runn runner Site?

I have been playing only in ACR for years because I am the only one allowed to play in Colombia, but I have noticed that in the last few months the number of hands I lose post-flop is too high. This includes all-in preflop and post-flop. It seems crazy to me, since players call without any chance and hit a turn-river flush. Has anyone noticed this too? or do you have any idea what it might be?
