[BUG][EDITOR] Pickup skill graphics not displaying correctly [FIXED]

[WillLem]

Whilst the Editor does write the correct pickup skill to the level itself, the graphic displayed in the Editor is incorrect.

Steps to reproduce:

- Open Editor
- Create a level with a few pickup skills from Timebomber onwards
- The incorrect skill graphic is displayed
