To reproduce:
1) Create new calendar entry with:
a) Repeated i.e. Daily
b) Start date is now
c) Never expire and set the end date i.e.: 1 month later from the start date
d) Send reminder emails
2) If the reminder time has come the LR sends a reminder e-mail
3) Update the Local time to a later date than the end date maybe 1 week (after end date 1 day usually send mail)
4) LR doesn't send any e-mail from this event
