Bug description

Logged into the game, hovered over the Active Quests list and the error was thrown as shown below. Reloading UI does not stop the error.

I have 20 quests in my active list.

Let me know what other additional information you might need.

Duplicate of #1868

We're targeting this issue for the next release. Unfortunately it is just not that easy to debug.

I experience this bug constantly when logging in.
I added a quick check for for a nil value and a notice when it happens.
Just now it popped up 10 times upon logging in with 8 quests active and zero tracked in the UI.

It's the same in line 791 and 807.
