act 4 bounty issue

[JiggaTheWigga]

hi

i am doing act 4 - 5 bounty and every time you get the one enter sanctum and clear chest it just wont enter in fact it keeps trying to find it???
another issue with act 4- 5 bounty is if it completes bounty it wont leave and keeps running around then jumps back to town and back into bounty again kind of like a circle...

also if i do act 1 five bounty I noticed after completing each bounty it just leaves and wont open horderic chest???

anyone having this issue

Regards
