KSP 1.0 and stack attachment node issues

[Gunslinger1]

I have been seeing a lot of node attachment problems with mods and the new KSP update. What's that all about?

[MOD - Split into a new topic, since it is a general enquiry rather than specific to one particular add-on]

Basically, in earlier versions of KSP, when stack attachment nodes for parts were originally defined, the direction/orientation did not matter.

In KSP 1.0, node directions now do matter, and are now strictly enforced. Many add-on parts packs used legacy stack node definitions that with oriented incorrectly, and so this is why the parts don't stack properly in 1.0.

There are numerous threads explaining the finer details on how to specify the correct node orientations, but that's mainly for add-on authors to worry about.

If you experience such issues when using an un-updated add-on in 1.0, please submit bug reports in the appropriate add-on thread.
