Crew Carrier Not Towing Trailers

Speaking on behalf of my alliance.
The Crew Carrier used to tow trailers, at least one of our players set up his boats to be towed by crew carriers but about a month ago he discovered that the boats towed by SUVs and pick-ups no longer were responding. The list of units says "tractive vehicle not available" even though the Crew Carrier is still in the station. This needs fixing.
