Hexblade Bull's Strength

[Svrtr]

It appears that hexblade's bull's strength is on a different duration timer than its other zoo buff spells. Call me crazy but it happens consistently and even now I am looking at my still lasting cat's grace and bear's endurance and my missing bull's strength

Expected Result
Bull's strength lasts 2 IRL hours along with cat's grace and bear's endurance

Actual Results
It appears to be on a turns/level timer instead of hours/level timer and disappears after 20 -40 minutes

After further testing, it seems to be inconsistent. It is hard to tell, but it seems that it does do that but only occasionally. What the trigger is I do not yet know, but I am going to try more

Are you Hexblade/BG? Could be that BG levels mess with it.
