My skill tree keeps resetting in a very bad way

Hi,
after a respec of around 15-17 points in my skill tree (deadeye level 81), my character became literally unplayable.
The respec points keep reverting to a mid state between the earlier version and the other one. Obviously the points are now not efficiently distributed, so the character is functionally unplayable.
Once I respec I can immediately see that the respec didn't actually happen and just by relogging I can find my gold back in my pockets and the tree in a messy state.

Can someone please help? I tried relogging many times and even wasted quite some gold trying unspec the points first and putting them back later.
Nothing is working. Please help I want to play :(

[UPDATE]

The problem is probably trying to respec travel node paths. Making sure that the two "ends" of the path are both connected first and THEN unspec one of the paths (borrowing points somewhere else) seems to fix the issue.
Obviously wasted more money to find this.
