First, I've been successfully using the Token Action Maker script for months; it's a real time and screen real estate saver when running combat encounters! I use the D&D 5e by Roll20 (2014) character sheet, and these are non-jumpgate games. During last night's session, when I tried using the token action buttons for an NPC that I had set up a long time ago, the action did not work but instead threw the following errors into the chat: I had created this NPC in another game and transmogrified it to the game in which we were playing about two weeks ago. I ran into this issue a few weeks ago with a different NPC and fixed it by deleting then recreating the token actions. Now that it's happened again, I pulled up the game where I'd created this set of NPCs and found that they all had the same problem with their previously created token actions. All of these token actions did function correctly when I created them weeks ago. While writing this, I decided to go back and see if I could learn any more specifics about this problem and learned that all of the NPCs where this happens are the variations of the kobold NPC: Kobold (MM1), Kobold Dragonshield (MMoM), Kobold Scale Sorcerer (MMoM), Kobold Trapsmith (ToB), Kobold Skirmisher (MME1) and Winged Kobold (MM1). The error occurs with all token actions except the ones for ability checks, which work normally.
