I bought Far Cry 6 from Connect for curiosity sake do we know for certain if the Epic version of the game does not work with the current trainer?
Yes. Trainer works fine with FC6 purchased from Epic.
How's the terrain and world regeneration going for everyone using the teleport option? Like if the world graphics reload well under a minute or if it's taking longer. Assuming it's on a high end or close to high end pc system.
On my system it loads in a few seconds at most.
How safe is the xp editor? Can I go all out and it shoot from rank 4 to 15 with all the shop unlocks in between or should I just go with entering just enough xp to have my next action raise it up one rank?
Just add 1 less then what you need each time, the rank goes to 20 which is the max. at Legendary. Do 1 thing that gives you rank points, and it will level each time without any errors.
