Saved Events: Crash when removing events on Saved page

[declanslevin]

Description of issue

The app is crashing when rapidly removing events in a somewhat random order. Although there seems to be something about the events around the 4th July which are consistently triggering the crash.

A precursor to the crash is usually that the card(s) is removed from the list but the list doesn't collapse to fill the space and the date header remains:

Expected behaviour

The app should never crash ;) Events are removed correctly and the list collapses appropriately.

Steps to reproduce

• Open the Events page
• Save every event from today until 6th July
• Switch to the Saved page
• Start removing some events in a random order, moving down the list
• Scroll to the bottom and quickly remove the events around the 4th July in a random order

Should first see the event tile being removed without the list collapsing
Removing some more events will trigger crash

OS / Browser / Device model

Galaxy S8

Haven't been able to reproduce this yet on iOS.

The bugsnag report for this should be #414

I've tried to reproduce this bug on multiple devices but am unable to. Maybe it was only those specific events causing the crash?
