When running a query like the following:
var query = nhib.Arms.Where(a => a.LeftHand.Thumb.Length == 1 || a.RightHand.Thumb.Length == 1);
Thumb alias was always taken as part of the a.LeftHand association path, therefore leading to wrong results.
I’ve worked on patch and test to fix this issue, so Thumb alias is once part of the a.LeftHand association path and once as part of the a.RightHand association path.
