Mike's packet has a l (lower case L) as overlay. Overlays need to be be
numbers or upper-case letters. It's easier to debug these issues by looking
at the "hex dump" version of the raw packets list:
It uses a monospace font that makes easier to distinquish between I and l,
but at least my display, makes l and 1 quite similar. Argh. Monospace font
that makes all of l 1 I different, anyone?

See the hex ASCII codes, 0x6c for l and 0x31 for 1. The hex mode can be
enabled using the drop-down thingy on the top of the display.
You could probably do the validity checking in YAAC too, to make the config
bug immediately obvious to users.
