I run minecraft 1.7.2. So, I already have IC2 experimental. I am using build 2.1.464 experimental. I want to know if I can upgrade to the latest build without having an error in an older world I have. Also I have to use experimental build in 1.7 right?
Also is there anything that I should be aware of that has changed since then? For example, I heard there is now a steam engine(whatever that does).\
Thanks.
