If you change the transition to this:
playerbox: Is outside layout
System: Go to layout "level1" with transition "None" lasting 0 MS
or this:
playerbox: Is outside layout
System: Go to next layout with transition "None" lasting 0 MS
then it will go to the next layout without any problems, so it seems to be an issue with the Fade transition. I've never used the Fade transition myself, I do all of my fades manually (with single-color BG Tile objects), so you might be able to do that as a work-around for now.
Anyway, it looks like a bug, could probably use a bug report.
