Re #228: Crash with missing abilityID * Quick fix to check if an ability ID doesn't match an ability and throw a standard error if it isn't found TODO: * Need to check why it isn't handled by the attribute type (IDREF) * Need to test it works! Problem shouldn't occur for <notes> because it is just a block of text and isn't referenced anywhere
