Simburbia isn’t broken. It was made using specific features in minecraft that came out with 1.8. Unfortunatley some game destroying bugs were found in those new features that Mojang implemented and now they took them out of Minecraft from 1.8.6 and onwards. Simburbia still works but you must start it in 1.8.5 or earlier for it to work. There is nothing I can do about it. For instructions on how to downgrade your Minecraft client feel free to watch this video. It certainly wasn’t my choice that this happened but that’s just the way it is.
If my video doesn’t make sense, there are literally hundreds of other that show you how to do it too. https://www.youtube.com/results?search_query=how+to+downgrade+minecraft
Any posts about not being able to find the natural spring, or the game being broken or where is the spring? I wont be approving. Have fun in Simburbia!
