I have tried the option in random places, open fields, farmlands, mountainous areas and in the middle of markets, none of which had any in-game icons selected and still cannot get it to work. It says activated and this has been pressed with the map screen open and closed (I have had success with this option in the past) it's the only option in the trainer that for some odd reason is not working for me.
Yes the other vote was me
Only thing that I'm now wondering was if me purchasing the in-game extra maps from the Uplay store has made some sort of change in memory and that is why I cannot teleport?
That's possible I suppose. I'm 99.9% sure Caliber doesn't have those xtra maps tho so it's doubtful they've been tested with the trainers.
You verified your file cache on Steam? Any info in the trainer's Debug file?
