A recent bug caused a small amount of our players to lose purchased items upon server restart. We are sorry that this happened and are working on compensating all affected players now that it has been fixed. If this happened to you, please visit this link: https://survivetheark.com/index.php?/forums/topic/422457-missing-purchases-upon-server-restart/ …
Unofficial owners just need to apply today's server patch and roll back to the last save before it happened. Owners can contact us for more info if necessary.
