The HeroLib project on CurseForge was last updated March 9th for game version 9.0.5, whereas HeroRotation and HeroDBC have both been updated within the month for game version 9.1.0.

I just ran into a NPE about an undefined method (Item:TrinketHasStatAnyDps) that renders HeroRotation unusable, and it looks like that method was introduced in HeroLib 9.1.0.04 (64e47c8) back in April.

I've verified that manually updating my local HeroLib to 9.1.0.04 has resolved the issue, at least on my end.

Thanks!

We know about it and are working with CurseForge to try to get it fixed. Unfortunately, their support runs at a sloth's pace.
