Hey yeah, ive had this problem too, i thought i was going insane – decided it would be smart to try the metrica province jumping puzzle – Rage quit when my jumps weren’t working haha :P
Yeah i agree with anubis priest, it seems to be more unforgiving the more you do it – Ive done quite a few in the past and ive never had these hopping issues, in fact its always felt very responsive and fair. I assume it happened after that new build earlier ^^
