I was following along with Nikradicals YouTube tutorial, and I keep running into Lua errors whenever I make quests that target NPCs (both with her tutorial and on my own quests). I have no other addons running except TRP3 and the extended. I am new to this, which is why I tried mirroring the tutorial, so I could ensure it wasn't user error. It still might be, and if it is I apologise.

Hi there, I finally got some time to sit and play around with this. It is still giving me an LUA error even after confirming. I think I am going to try to go through the "Cow Level" tutorial again fresh when I have some time as I think I might have missed some things. If I am still getting errors I will post again. I really would love to get this going for my guilds.

Hi. Are you using version 1.2.0, or 1.3.0 beta ?
Also can you right-click on your creation, select quick export and copy-paste the content of the textbox here ? This way I can check if I can reproduce the issue on my end or identify what might be happening.

Hi thanks for the quick response. I am using 1.2.0,

Alright, I think I'm seeing what's causing the issue. For the time being, when you select a condition in the dropdown, make sure to click Confirm in the yellow popup below the dropdown.

For your existing conditions, you can click Configure below the dropdown and the popup will open again for you to confirm.

Let me know if this solves your issue when you apply it to the conditions in either your or Nik's campaign. I'll look into securing the condition system to avoid that issue in the future.
