I'm very confused about bubble trees. I'm pretty sure they used to be all over Kajuu before they all got replaced with beans and fruit... but when I found an empty patch in Kajuu early this morning it wouldn't let me plant a bubble tree bean there. (Yes, I did tend the patch before I tried. Yes, I know I can plant bubble trees in my back yard. Thank you. Let's move on.)
What the info box on the bubble tree bean said was, "Must be planted next to a clean patch." I'm not sure what that means. "Clean patch" I understand; "next to" makes no sense. One plants IN patches, not NEXT TO, right? Maybe it's really obvious, but it's going right over my head! Can some very kind and patient Glitch explain?
(I did take a look at the Glitch Strategy wiki. It listed which "continents" bubble tree beans could be planted on, Grumbla being one of them, but it didn't mention any other planting restrictions.)
