When using the alternate cast button option and setting it to Mouse2 / right click / [zoom], the ability will not self cast. It shoots alt fire instead, cancelling the ability. I believe this to be a bug because using this button mapping worked in the previous version.

I tested using another key for alternate cast, and that worked normally. This issue is indeed only with right click.
This is having some other weird results as well. For instance with Dynamo: If I want to teleport myself + allies I now have to hold right click, then hit ability button followed by left click. Not very efficient
