If you're as crazy as me who tried this mod on my main account, which reset all my achievements, progression, and fbi files. This mod is for you!

What it does is, you get a 1/6 chance to have your account reset on mission completion. (chance can be changed at line 51, just change the 6 in "math.random(1,6)" to any chance you want (1/x chance))
Like I just said, it resets both achievement and stats, but also like a normal reset, your progression !

Credits to the Full Clear Progress mod that I pretty much used to find the code to reset achievements and stats.
Also credits to Dr. Newbie's One Life mod that I shamelessly stole code from for the quick menu message when you get reset, and the simple tweaks (deleting inventory, resetting the infamy tree, etc...)
