unable to create new event location without impacting other events
to reproduce this issue:
- create an event. on the location tab, create a new location with the street address "test address 1"
- return to the manage event screen. click more > copy to copy the newly created event
- select the location tab -- it will already have "test address 1" selected. click the option to "create new location" and add a street address "test address 2". save the event.
- return to the event management screen and click configure > location for the first event. note that the address now references "test address 2"
you should be able to create a new location for an event and it should have no effect on existing events that previously shared the location.
