Despite the expectation that only validated events are stored in the
database, instances have been identified where invalid events are saved.
This can lead to unexpected behavior or crashes.
This commit adds validation for community events read from the database
to prevent such cases.
**NOTE**: this fix does not address the root cause, which involves
invalid events being saved to the database. The exact scenario leading
to this issue has yet to be identified.
