+This function is a workaround for a suspected ACE glitch.
+
+During unloading of mortars quite a lot of them disappear. 
+They are then located below the surface.
+
+Using this function they are being brought back to the surface.
+
+See https://github.com/acemod/ACE3/issues/10010 for more information.
