Bug #13038
Fuel transfer fails after undock/dock when root part is on side with less mass
100%
Description
Fuel transfer fails when the root part of the ship is on the side with less mass before undock.
After undocking and redocking (to same ship or another ship), right-click on fuel tanks to start transfer shows in/out on the unaffected ship, but not on the affected ship. Clicking the in/out on the unaffected ship does not move fuel to or from the affected ship. Other resource transfers (e.g. electricity) work normally.
Clearing the "Resource transfer follows crossfeed rules" option allows the transfer to work.
The attached files demonstrate the issue. To replicate:
1) Deploy "Bad Crossfeed" on the runway
2) Undock and redock
3) Attempt fuel transfer across dock
The lighter side from "Bad Crossfeed" will not transfer fuel after docking. The heavier side transfers normally.
The "Good Crossfeed" craft has same parts, but the root part is on the side of the dock with more mass. Changing the root to the other side of the dock makes "Good Crossfeed" bad, and "Bad Crossfeed" good.
This is tested on KSP 1.2.0.1586 64-bit on Windows 10.

Updated by I get an "Internal Server Error" when I try to attach either the craft files, or a zip containing them.
The craft is at follows, from the SPH perspective:
- Root is Octo
- On the right, a half-full Oscar tank and Z-200 battery
- On the left, a Jr. docking port
- Supported by 4 S2 powered wheels
The craft is mirrored on the other side of the port, with an extra 3 Oscar tanks.
I'll try uploading the .craft file again later to see if the problem is resolved.

Further test shows that this doesn't happen if there's no probe core on the heavy side.
Also, when the ships are joined, the "good" combination has a probe core as the root node in the .sfs, while the "bad" combination has a docking port as the root node. Don't know if it's relevant, but it indicates the ships end up structured differently.

With version 1.2.1.1604 from Steam, fuel transfer works as expected on both the test ship described above, and on the stranded ship that originally prompted the bug report.
