Every time I either go into the nether and come back or reopen a save file, I have to respray my crops with weed-ex. I first discovered this bug when I reopened one of my world files and suddenly, weeds came on a cropstick. I sprayed it and got rid of the weed. Just to make sure this was a bug. I closed and reopened the file again and moments later a weed grew on the same cropstick. I am starting to get tired of it. Please fix in the next update or release a patch!
