Welcome to the forums. I'm sorry to say I actually fixed that bug long ago, but I've been a bit sloth in releasing new versions, aside from auto generated nightlies.
You can always grab the latest nightly from the download page
, however bare in mind these are experimental builds created via our CI server. This means while they have had some level of automated testing and deployment checks, they haven't been installed and tested by an actual human. So while they may be perfectly fine, they equally may crash and burn (especially the current builds from 2017 as I rework the internal mess made of the palette formats and editors).
Any of the available nightly builds should resolve the specific crash you're experiencing - but I do plan on (finally) releasing new stable versions soon once I've finished some documentation housekeeping.
Hope this helps - glad you enjoy the product!
