I think I have found a fix for this @web541 @HCStrike Remove your
<script async defer src="https://maps.googleapis.com/maps/api/js?key=PLACE YOURKEY IN HERE&callback=initMap"></script>
from your core_htmlhead.php and put into your acarsmap.php just before
<script type="text/javascript">
var acars_map_defaults = {
autozoom: true,
zoom: 4,
mapTypeId: google.maps.MapTypeId.TERRAIN,
refreshTime: 10000
};
</script>
Its a crew center error that is calling the scripts multiple times.
