Kraken Help Required

[Lithobrake]

I recently docked two large structures to each other in LKO. No matter what I do, they always get the wobble of death, and explode! I've tried turning off SAS and Quick saving, but They need to be able to turn, and go to Duna! The part count is 479. Help!

Check for anything on either vessel that may be auto-strutting to "heaviest part".   If so, turn that off and try again.   If, after docking, the heaviest part on one vessel is no longer the heaviest part on the whole thing, all the auto struts will have to connect to the new part, and that can cause a wobble.

If you want to, you can use the debug menu to cheat while they are docking, and then once they are completely docked you can turn the cheats off and see if it'll fix it

Thank you! I've tried turning auto strut off, but it didn't help.
