unsafe? no..every version has the same protection against warden. but if you mean unsafe in a way of buggy,yes! use 1.331. its the most stable version atm
I would recommend using the HB2 beta while you are around and able to catch it doing something wonky, and use HB 1.331 when you are afking. this way, more bugs will get caught/reported/fixed, and HB2 will move forward faster. kinda like blizzard and the PTRs, if nobody played them whats the point.
