So to sum up, you made a coop, went inactive for a long time, and your coop mate left with your beacons. Since they're still in the economy, then simply adding more beacons would cause illegit items to be spawned in. If you were around in 2013 then you'll know that you invite coop members at your own risk. Refunding beacons in this setting would only cause illegitimate items to be spawned into the server. Hope this answers your query.
