Convoy stuck on train tracks - part 2

May have finally found the issue.  Found RF C4 left behind on the tracks after it got stuck again.  Was able to duplicate the issue.  Also placed some down before the tracks.  A bradley did pick one up as it was driving over and then became stuck on the tracks down the road.

Thanks for the information, I'll try to fix it

Fixed

Still happening with 2.6.3.  I was able to scan around under Bradley using remover tool in admin mode and remove several C4 from it.  It started moving again once I cleared them.  Can't really see them, just have to slowly scan around for them.
