The ACE3 alpha solved the bugsack / buggrabber issue and the viragdevtool error was, in fact, an error. I fixed it by changing the reference ViragDevToolOptionsToggleButton to ViragDevToolButtonTemplate in ViragDevTool.xml
Good news and bad news... I fixed the infinite loop error in Skillet, but its not throwing any errors so I can't verify that bugsack / buggrabber are working!
I'm sure that will change (errors in Skillet) but they will be difficult to find as all my template 110s have skill level(s) of 1 and I'm not sure I'll spend my beta time leveling professions.
