Running latest spigot server 1.8 which seems to be running fine.

The EpicQuest plugin starts fine (default installation) using Vault as required.

I created the quest and placed a villager assigning that quest to him which works. When I click the npc I get the quest start text but then thats all, my questbook never updates to show that I have a quest in progress.

After such, if I restart the server I get the following error:

[19:46:31 ERROR]: Error occurred while enabling EpicQuest v3.5.4 (Is it up to date?)
