Hello,
I'd like to let you know about a bug i'm running into for a while.
While working with transparency of attachments on beziers (that's important), spine sometimes let me set transparency to values, as mentioned in the title, below 0% or above 100%.

It results with flickering attachment in the runtime. The easiest way to reproduce this bug is simple - just make a key and set one of bezier's handle above 100%, for example. I'm not able to attach a video, but i hope my description is clear - if not, just let me know!
I've checked - problem occurs ONLY while separating alpha.
