8/10 – Necessary Evil
Update 1.608.0.3 / 1.607.4.9.3 is not a content update; it is a security lockdown. For 90% of the player base, this is fantastic news. The economy feels fairer, and loading times are slightly faster due to optimized VRAM.

A small group of reverse engineers discovered that the “E” exploit can be reactivated by hex-editing the executable to revert the JMP instruction to a previous state.
