/usr/local/share/terminfo.db previously backed up to /usr/local/share/terminfo.db.default The script /usr/ports/Keywords/terminfo.ucl (run in this case by x11/kitty install) nuked my terminfo when run. It blindly copies terminfo.db.default to terminfo.db before running tic on new files.
Thank you for the report Jamie
The changes to use the terminfo directory tree instead of the terminfo.db database have made this bug report obsolete.
