ok, thanks, fixed in 95c2a25
Did you encounter that often?

Since I started using this addon today, I got 2 errors in like 2 hours of playtime.

It's just very weird that I've never seen this before, considering it should've been popping up every time someone joins in combat

Could that be Blizzard changing something in the client maybe?

Not without a client patch. Well, whatever... I released an update with the bugfix included, so get that if you haven't already https://github.com/rgd87/Aptechka/releases
