Granthika Mac OS freezes, loses changes when setting event relationships

When adding a second chronological relation to an event, the Granthika app for Mac OS freezes. Some interface responses, such as button hover-over changes, continue to work but the app does not respond to any mouse or keyboard actions. This occurred twice today, both times when adding a second chronological relation of the ‘before’ type. The first relation is of the ‘after’ type.

My only alternative is to quit and reopen the app, whereon I find the most recent two (I’m fairly sure) edits to events’ Details page are missing.

After relaunching, I entered the text above as a bug report.
