I am having trouble reproducing this. I was able to reproduce this the first time that I attempted this, but was not able to diagnose the problem fully without more extensive testing. However, on further testing, I could no longer reproduce this, and, despite many, many attempts, I have not been able to reproduce this since.
The problem appears to be related to the same transferring cargoes code as caused the original crash, and so may be related to the fix, but without being able to reproduce this reliably, this will be impractical to diagnose and therefore fix.
Is anyone able to assist with a more reliable reproduction case than the instructions so far given, since these do not appear to work in many cases?
