Client crashes after using Paladin's 3rd job skill "total crash" with the following message, "Error code 5, access denied". It happened 2 times at zakum today, but can confirm this is not a boss-related issue since it happened to a friend of mine after casting it randomly in town. Edit (15/12/18): Fixed in update #58
Can confirm, Both me and a paladin friend had it happen a number of times at Pianus this weekend. Total crash really is TOTAL.
