I use Twitch to update and would love it if you put new patch for addon there! :)

If you are using the alpha version of HeroRotation, it requires that you also use the alpha version of HeroLib.

Where can I get the Alpha version of HeroLib?

If you update via the Twitch app, right click the addon, go to Release Type, and select alpha.

Otherwise, you can download the alpha versions here:
HeroLib
HeroRotation

This still appears to be an issue. I appear to be up to date with both alphas on the Twitch client.
HeroLib-8.3.0.00-17-g95b5dbe-alpha.zip
HeroRotation-8.3.0.00-171-g06585e2-alpha.zip

I'm not getting it on every fight... running a lvl 99 at the moment.

The addon isn't guaranteed to work for characters under max level. If you provide an exact error, we can take a look at it, however.

Edit: sorry, didn't think I needed to post it since it appears to be identical.

Took one of my rogues out yesterday with no problems. After a while, though, I swapped to Asn because I'm so tired of Roll the Bones RNG. Thanks for checking into it!
