Having bugs on at least every mastery challenge i have done.
[MAIN]
.Wolf challenge on Lolingstone Targets spawn outside play area.
.Raven challenge on Odins mine, was on platform above final kill, Eivor swung arm and made a ground execution despite being above target [also targets not allowing air execution even when above].
.Wolf challenge Templebrough, Explosive barrels which are essential, have already exploded upon loading mission.
all i have encountered so far as it has taken hours to find work arounds or just complete due to these issues.
Honestly would be a non-issue in the main game, but as these challenges take such precise execution and large amounts of time, bugs that stop completion should truly be non existent in these challenges.
