Wasn't quite sure where to put this as it's not a support question but it seemed like a good place. :/
Just spotted a typo in plugins/events-manager/buddypress/bp-em-templatetags.php on line 19 'evebts'.
$slug = !empty( $bp->evebts->slug ) ? $bp->events->slug : BP_EM_SLUG;
I have no idea what it means but thought it worth a mention. :)
