Hey there ownedcore. I'd just like to show you how to get three specific error messages when you want!.
Mail Error:
Spam shift click your mail and occasionally get the error "Internal mail database error." Postal may be required but not sure. https://i.imgur.com/onhh7zW.jpg
Auction Error:
Make sure u set it to something (works better) approximately 5 or higher auctions at once and you can see the little auction bar at the bottom of your screen showing how many auctions of gone through. Well at that time just step back so you are not in range of the Auctioneer and you receive the error: "Internal auction error.". https://i.imgur.com/4XwhRsW.png
Internal Error:
I have only tested this with prospecting but might also work with milling. (don't use macros for this 1). You have to manually click prospect on an ore and then click it again on the same ore when the bar is just about completed. Sometimes it says busy looting or just cancels the process but sometimes it comes up with the message: "Internal error". https://i.imgur.com/SWpvuE7.jpg
Idk if anyone can find anything with it. Wasn't an exploit but ment for exploiter's to see if they can get some profit out of it. Enjoy!
