Im unable to see the aura timer while testing the addon on the SoM beta server. Not getting any LUA errors. It works fine in the TBC version.

Addons can't get duration of auras in Classic. It is the API restriction.

I understand thanks for clarifying.

Im not familiar what they did, from what i know Classic Era servers are running on the TBC client.

Somehow ThreatPlates are able to display the timer and the spinning circle.

Hmmm. Okay, I'll look into it. Restictions I've previously mentioned were active on Classic servers one (or two?) years ago, may be situation is changed now.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

I know it's may be too late, but I've made the initial release for Classic servers.
