Thanks for testing. Martin merged the fix into master.

Known (by me) issue. I thought I also filed a ticket for this but could
not find it now, can you do that yourself ? Please add the "rotation"
tag in the report.

Generally speaking, there are many places that need to learn about core
rotation. Searching the tracker for issues with "rotation" tag is a good
starting point.

I've only had enough fundings to add the core support. I'll work on fixing
any regression in absence of rotation (like the "jumping" one) but will not
approach further enhancements until I either have some spare time or find 
more sponsors.
