Already bought The Last Word from Zur a few weeks ago, was ranking it up slowly. Today, I visited him and saw that an upgrade was available for it with an exotic shard, glimmer and if you own The Last Word. I didn't see that it made much difference with upgrade but thought "well if it's telling me I need those 3 ingredients, there must be an upgrade, especially as bungie would have put a fail safe in place to stop you wasting stuff on a non existent upgrade" I was wrong. Nothing happened and now I'm an exotic shard and about 7,000 glimmer out of pocket. This surely must be grounds for recompence?
