Hey Amuzis, just in case you were' not welcomed with your first post, welcome tot he forums!

You (obviously) should not be getting this error and since I haven't seen it from others it is probably coming either from an incompatible extension or a custom ruleset. Try again in a new campaign without enabling any rulesets. If it still persists, then open your FG data folder and check your "rulesets" folder to make sure you don't have any unpacked rulesets (i.e. directories).

Let us know if one of those resolve the issue.

Problem is sorted turned out that vitality point ext was source of the problem.
