This seems to be 50/50 between players
On one hand I can understand the players who missed out due to the expiry date but there was a post both here and facebook saying they would be extended after the event.
On the other hand, if players decided not to make them why should they just be handed them or given an extra chance to make them, it is unfair on the players that went to the trouble to make them.
What I am thinking of doing is readding an expiry date to them and working on other items for the slot, that way players that missed out will be able to get other items for the slot and players that made the item can use it for a couple more weeks.
I feel this is the fairest thing for all players.
