i jjust figured out y sugarcane pops out randomly in large rows... it is due to render distance.. the cain renders in but the water doesnt so the cain doesnt detect water and pops out way to solve this would be X_X_X_X_X where X is cain and _ is water
This is indeed a known bug and I can confirm that this is happening, sadly, we're not quite sure what's causing it, but what you claim is likely not it, I've had this problem with a "_X_X_X_X_" setup, too. Usually this isn't a problem though, it's usually a single row and only a 5-30 canes.
I have a sugar cane farm and it has 2 rows on every level which disappear. Some glitch I believe that cannot be fixed. MY setup is WSSWSSWSSWSSWSSW... W-Water S-Sugar
