I am having a bug regarding Fredrick NPC. I am unable to retrieve my items from him in order to reopen my store. I see this is a bug reported in the past. I first noticed this about 2 days ago and has not resolved.
"Fixed an issue that caused Fredrick to temporarily not be able to return your items if you had used the collect meso button inside a Merchant." Update 96 - https://royals.ms/forum/threads/update-96-11-09-25.249695/
