Falmouth dockyard bug (again)

Attempting to timetable a train into the docks and have come across a small problem. The train has arrived at the docks and the shunter has telephoned Truro box about the staff. I have a train that is due to enter in 10 min or so so I have told the shunter to retain the staff at Falmouth. However, the original train never actually 'leaves' the sim, instead being caught in an infinite 'terminated, no more timetable tips' condition. Which then causes major problems as not only is this train stuck forever, but also the staff is now stuck at the Falmouth end with it, with no way in which the return working can leave the docks, thus returning the staff

Please could this be looked into, ta'.
