Change “No event found!” Message

How do I change the “No event found!” message that is shown when a shortcode doesn’t have any events to show? This isn’t proper English, should be “No events found!”. I looked in the Messages area in the plugin settings and this phrase wasn’t included there. I’d think it should be, this is a pretty important phrase in an event plugin. Is there any way to change this via a filter within the plugin? I’m not going to install a translation plugin just to change one common phrase, this should not be necessary.
