Trouble undocking two rovers

[Ozelui]

Hi, 

A couple days ago i found this bug in my current game:

 

Both the rover and the trailer were created as part of the same ship originally, once in Duna they were decoupled independently and i docked them later to transfer LFO to the scout rover from the mining trailer.

The rover appears to float after undocking, but it is still connected to the trailer.  When time warp is activated all the rover parts return to the original position as if it were docked.

I'm playing 1.3.0 x64, with just one mod installed, KJR v 3.3.3 (up to date).  I tried to delete the mod and load the scene again, but the rovers have the same behaviour, so i'd say is not related to the mod.   I also tried to modify the persistent file using KML 0.7.2 to fix all the docking bugs,  but the problem persists.

Connecting another rover with a claw didn't fix anything either.

Any ideas?
