Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Troubleshooting Ability modding breaks teleport gloves?

I did some modding this weekend, mainly changing abilities but also some talents, attributes and civil abilities.
When I did some testing in singleplayer everything worked out as expected until I got to the crocodiles and got the teleportation gloves.
For some reason these don't add the teleportation ability anymore. The ability is still shown on the item but equipping the gloves doesn't grant lead to the new ability popup or the skill popping uo on the action bar or within the ability screen.

I changed the teleportation skill somewhat (reduced range from 13 to 10, increased cooldown from 4 to 5 and increased requirement to aerotheurge 4) but this shouldn't change anything in regards to the gloves. I didn't change the story world at all and the only items I changed are grenades and arrows.

Any idea what happened there? What could be the reason for this? How could I fix this issue?
