Here’s what i did: i have unwrapped my UVs and cleared my seams.
Then i pinned certain UVs.
i created a new seam
Now all my pinned UVs are “joined” and criss-cross at that!
I don’t want that, i want to reunwrap without the UVs i pinned mysteriously joining criss-cross. i don’t want my pinned UVs to change but they change.
