And how is that a idiotic suggestion?
Sir, you clearly dont know the game well, because there are coconuts, but obtained from crafting coco and nut (same like pineapple, guess the crafting for this one). Also I dont think palms are supposed to grow (mainly) in the jungle, THEY ARE, but they also grow in oasis? On the beach? Dont you got this in wurm? Well I'm super friendly user but I need to say that, only idiotic here is your comment. I don't blame you for not liking the idea, but I wanted to make it straight. Adding one tree type, which is not a big deal let's be honest, will change the look of deserts and coasts. I dont want to look like palm maniac but I was thinking about this for couple years, cause I always deed at ocean coast.
tl;dr you are wrong that there need to be "jungle" to make palms have sense.
