Ok but I am probably gonna be in 1.6.4 also I am not sure if the mega rubber tree is the sacred rubber tree because when I went in creative I found out there are two sacred rubber saplings 1 is a mini version of the sacred rubber sapling (which I will probably chose for my base) and 1 that is enchanted and it is the full version
Well couple of things 1. Is that I tried spawning in the sacred rubber tree on a flat world in 1.7.10 with a couple of mods and it didn't even crash my game I have a 32 bit pc so I can only imagine what it will be when I am on a normal world with tekkit
The reason why I want a sacred rubber tree as my base because it is so big it can make a awesome tree house out of it
