Most of the information on this page was directly taken from the May 3rd 2015 version of the rs3 wiki. The problem is the rs3 version received an update in 2015: Update:Impetuous_Impulses_Improvements. I have been checking with the Wandering impling over a couple days. As far as I can tell, the crop circle locations of the sister field that I have left in on the page are the only ones that exist in osrs. I haven't confirmed how long the crop circles stay, but the Wandering impling says half an hour. I also removed one of the trivia bits because it refers to "Magical wheat" in Puro-Puro and not the crop circles:
- When passing through the wheat when it is about to shrink into the ground, when you are halfway through you will stop and the text "The wheat here seems unusually stubborn. You cannot push through." appears.
