Hi Alan,

M0x0 is an empty signbox in the middle lane.  You found a conversion error.

In SignPuddle 1.5, the SignSpelling Sequence for diaper used 2 detailed location symbols.

In SignPuddle 1.6, the detailed location symbols have been dropped.

Across all of the various puddles, there appears to be a couple dozen such problems.  I'll investigate this further and fix the errors first thing next week.

Thanks for the QA work,
