So I added another mod to my MC 1.7.2 and Pam's HarvestCraft is certainly very cool by adding a new level of complexity and fun to crops and farming. I read more about this mod on its wiki page and noticed that there are new food trees as well as crop seeds. I looked through the config file and confirmed all the ___treeGeneration lines were true. Do you have to start a new world to find these new food trees? Or will they be generated in an existing one as well?
I'm hoping Pam will confirm this, but a reply from anyone with more experience using this awesome mod would be appreciated.
Sorry for the double post. I answered the question on my own and am posting this FYI for those interested. If you have an existing world and you add HarvestCraft to your mods list, *existing* trees won't suddenly bear the new fruit, but *new* trees will. So if you explore part of your current world in which the chunks haven't been loaded yet, the new generated trees have a chance of bearing fruit for you to harvest and combine with saplings to craft the new fruit/nut tree saplings for you own farming endeavors.
I did notice the whole tree thing but what I thought was weird was that such trees grow wherever they want. Like I see fruit coming from jungle trees every which way, even outside my house, yet the closest jungle biome for me is 9000 blocks away. It's just something I noticed.
