Hey again,
We have just pushed an update to the roller-beta branch with a fix for the following bug:
Clicking on the "remove" radial menu button while the cursor is over a d4 or d6 could cause an exception.
We only have one other known bug, and that's for the dice on the login scene[0], so we are looking good for a release soon.
Thanks for the help, folks!
[0] We have a fix for this already. It will ship soon.
