Floating debris

[maxiking66]

The bot does not destroy these floating debris, which are a kind of barricade in the mysterious cave in dahlgur oasis A2. I'm guessing there are some more of those things in the d3 world. I have destructible attack range at 10. Dunno if that is the setting that should help here.
I'm guessing he tries to clear it with ancient spear on my furious charge barb, but when he has no fury that does obviously not work. I tried setting unforgiving as a passive to generate fury for ancient spear, but he just uses sprint while standing there. In the build is furious charge which would work to clear the objective but I don't know if or how I could set that up, so he uses that. And if that is not possible to set up is there an other way to get this fixed or do I have to run a normal primary skill with which it would work?

You can try increasing the destructible attack range at 45
