Code Issues

(svn r9345) [0.5] -Backport from trunk (r9277, r9337, r9338): 

- Fix: shared orders got messed up when the 'first' trains got removed in the depot (r9277)
- Fix: assert() when you removed the orders of a shared list while having the shared order vehicle list open (r9337)
- Fix: close the Shared Order Vehicle List if you remove the shared link with only 2 vehicles (r9338)
