Have the rules for Datatypes changed?
In a personal book of hymns I previously successfully used the milestone "126 [[@Headword:126]]"
And elsewhere the link "[[126 >> Headword:126]]"
But using numbers only no longer seems to work and link is dead.
If I change the format to include an alphabet character then all works ok. In the above example adding an "h" to the digit "126"
"126 [[@Headword:h126]]"
and
"[[126 >> Headword:h126]]"
Any ideas?
