Hello! There's a 100% reproducible 'rotation after re-root-save-load bug for the BZ-52 Radial Attachment Point' in the unmodded KSP 1.12. It was reported about a yea ago (still not fixed):
https://bugs.kerbalspaceprogram.com/issues/28593
Here's a short video example (1- place a tank and then the radial attachment point, 2- re-root (!) to the latter, 3- save/load this assembly and 4- each parts should be rotated in wrong directions):
Anyone would like to try to fix it?
I'm not sure the BZ-52 is the only part bugged this way.
