Missing Information in Skill Info Tab

[sonic glade]

Description of the Bug:
In the Info Tab of certain skills it's supposed to show information about the skill. In my case, f.e. with Lore, I am not seeing any information except for the current level.

I don't have all skills unlocked. But of those that I have unlocked, those skills affected:
Lore, Cartography, Fletching, Meditation, Milling, Performance, Teleportation

To reproduce:
Open the Info Tab of the listed skills. Some players reported that they also have the bug, but others do not have that bug. So if it's not reproducable on your machine, we can reproduce together on my machine as well.

There's probably some error causing this that's being printed in your logs, can you open the window to one of those skills to force the error, and then send me your log? Any skill should work except cartography and performance; they don't have any additional info to display there so those ones aren't bugs

The log is in (on windows): C:\Users\<username>\AppData\LocalLow\Elder Game\Project Gorgon, named "Player.log"

Here is a section of my logs in which I triggered the bug. I assume

IndexOutOfRangeException: Index was outside the bounds of the array.
  at UIAbilitiesController.UpdateAllTabs (SkillType skill)

Could be it

Also, on skills that work, the selection of that skill is highlighted in green on the left side:
