Best way to report bugs in the beta?

Hi everyone! I've been playing the current 2.2.0 beta 0.3 version of shattered, and every time I have a stack of two scroll if remove curse and I use one, it consumes both scrolls. I haven't gotten to test yet if it clears a whole stack (3+) or is just using two. What's the best way to flag this for Evan to see? Thank you!
