What causes this issue? How can I reproduce the problem myself?

If I log into Wrath Classic and cast some spells, it works fine with no errors.

I'm not exactly sure what causes it. I'll have to be more attentive next time. My guess is that alpha is nil when the error occurs.

I'm playing Wrath for a few hours almost everyday and for the most part, IceHUD behaves. If you were to provide me with some debug / troubleshooting code to add to that function when alpha is nil, then I can hopefully capture more information the next time it happens.

I'm not sure any additional code would reveal anything helpful. I went ahead and pushed an alpha v1.14.22-alpha1 version to see if that fixes it. It'll be available on the CurseForge app if you switch IceHUD to alpha builds or at https://github.com/parnic/ice-hud/releases.

I've updated to the alpha. I'll let you know what I find.

Did this work?

I haven't had any reoccurrence so I think its fixed.
