A new build has been pushed for Windows and Mac users. For Mac users, this should significantly drop the CPU usage across all sections of the game.
For Mac and Windows users, this update adds a DNS fallback for users who may be on networks where the game's domain name (idlehacking.com) may trigger filtering due to the word "Hacking". If the game detects a connection failure due to a DNS resolution failure, it will attempt a fallback to ih.gigaforge.com instead.
