Collisions are not checked when a recurring series is “reset” (by saving the series) and a new event already exists at a previously deleted recurrence’s time:
Steps to reproduce:
- Delete an occurence
- Create a new event in its place
- Edit the series (no modifications needed, just click “save”)
Resets the series and (re)places the deleted occurrence next to the newly created event (does not respect limits / does not prevent collision)
Does not allow series save / reset.
Obviously, this does not fire onEventCollision. Workaround appreciated.
