it loads forever
glad to hear that it has something to do with the rotation axis
indeed I rotated my part so it was totaly horizontal
and now it takes forever to slice
then once I cancelled it, I just cannot restart the slicing anymore
The OP reported this as an issue almost a year ago...and since then there's been a major and a minor software release...the latter incorporating some bug fixes that I believe relate to the software hanging........so I can't see very much of a link between that issue and the one you are having now.......unless you're on a pre v4 release of the software. In which case, I would seriously suggest you upgrade to the latest release and then see if the hanging continues.
If you're already on the latest release then I'm sure the Devs....who you accuse of denying that there's a bug even before you report one......would appreciate you posting as much information about your particular issue so they will have the smallest chance of replicating your issue. Once replicated, they more than half way to getting a fix!
