A lot of changes have been made to our virtual stick controls recently. The goal was to make the maximum speed go from 10 m/s up to 15 m/s. Also changes were made to address reports of aircraft bucking. Other optimizations were also made. So yes, you will see differences in how their aircraft flies between the last few versions.
It should be landing on its own still though. Please post the link to your affected flight log so we can take a look.
