I'm having a LUA Error with Big Debuffs & Tell Me When.
I've been using Big Debuffs for almost a year & recently downloaded Tell Me When to track my Holy Priest Divine Conversation Tier Proc.

In doing that, it has caused my Big Debuffs to stop showing up on the right hand side of my nameplates.

They work on the target dummies and the "Test Mode" works, but in world pvp / arena / bgs / skirms, the Big Debuff does not show up.

I do have the boxes checked to show up in these situations.
