Anyway to fix this? Or recover from the fact that my whole perk tree literally just vanished after I saved?

Not that it matters on the latter since the goal of my mod is to actually replace the perk trees.

However, it still leaves me with this issue. Every time I add a perk to a tree, click OK, then go back into it the tree is WIPED clean and appears completely blank (including the perk I added).

This happens every time, and I can't figure out why. Any help?

I couldn't reproduce the problem. It works fine for me.

Odd, just started working for me as well. I guess I'll just have to double check everytime I make a change to the tree so I don't accidently save a deleted tree.

One of my perk trees has vanished too... after I added two new perks to the smithing tree and repositioned the perks.

It still worked after adding the perks, but the new perks where located too close to the next tree. So I repositioned all perks and now they are gonne....

Hope we will find a cure for this!

edit: okay, rebuilt tree from scratch is fast and easy.... FIXED!!
