I think the bug report was from me. There was a problem with some
versions of cheap (before May 6) being compiled against older vpm code
which has meanwhile been fixed. 
See Stephan's mail from May 6.

I would have though so, if you're using the Matrix 'event-relation' for them.  If so, they should have always been getting printed as 'e' in the resulting MRSs.  In the LOGON universe this external mapping of the MRS is mediated by the variable-property-mapping, typically defined for a given grammar in a file with a .vpm suffix.  If you are using such a file in your Wambaya grammar, see what it says about 'event', and maybe compare it with the file 'semi.vpm' in the ERG.
