Attach nodes get reset in dock mode on RTS

[ihsoft]

From the forum:

I got it reproduced.

1. Have a set of surface attached parts on a main body.

2. Connect resource transfer station to a connection port on one of those surface attached parts

3. Switch to Docked mode

(At this point quicksave shows the tanks are srfAttach, 157, 157 and 152; I presume that's the main body (EL survey station) and the hose connector leading to the mining base root node respectively)

4. Grab the connector with a Kerbal

(Now quicksave shows the tanks have srfAttach numbers of  0, 0 and -1, and the fuel flow treats that tank and its attached children as a separate vehicle)

I don't see any log files, but I deleted them before making the attempt, to try and narrow things down.  I guess I'd need to restart to get the logs flowing again.
