Reminder schedule event (timer) is not working sometime

@amn41 sorry for late - i use ReminderScheduled event after every message received from user to wait user answer for 60 seconds otherwise bot will call an system api to join an agent - and reminder will automatically kill once same user send any message.

so, i am facing an issue sometime reminder is not call my action ‘action_handoff_timer’ even i schedule it by return [reminder]

and here is my logs of action server - you can see at 17:09:14 i schedule a reminder for 60 seconds but action not called by rasa - even as you can see customer send a new message at 17:11:16 and bot schedule reminder again and this time rasa call that action see at 17:12:16, exactly 60 seconds latter which is perfectly fine

so my problem is - it is not reliable sometime its not working for me
