v2/traits has an array "skills". For me it seems like the skills listed inside there are the very same the v2/skills gives, together with all facts/traited facts.
This seems like duplicate information.
Wouldn't it be better to make an array of integers for the skills and let people resolve them against v2/skills?
Was I able to help you or give you a hint? Click on Helpful and/or Thumbs up, I would appreciate it alot!
When you encounter a bug ingame, at first you should file a ticket via the ingame command /bug, as only this way the devs will know exactly where you were, when the bug happened.
