Problems with physics range extender

[TheKspEngineer]

When I was flying in low orbit over a landed rover on Minmus, it switched to the rover (which appeared to be in outer space), and my original craft blew into pieces and started to fly out of the solar system. 

I did this fix and after while I tried to land near the rover, it did not switch to it. But when while landing I tried to switch to it with the hot key it appeared to be again in outer space. I tried to switch to space centre and back to the lander, but then the rover on the surface just exploded.

Physics range extender is know for causing this sort of issues... what I usually do is turning it off and as soon as I get into the stock physics range of about 2.3 kms I turn it on and then have fun with it... I mainly use it for BDA, tho it might prove useful for many other things

Why use Physics Range Extender at all?

Because bdarmory needs it

Thanks will try that

I think there's a fairly obvious next question there, given that you seem to have hit this problem while trying to transfer crew to an Elcano rover, which doesn't want much in the way of guns...
