hello, i am quite new to tekkit but absolutely love it. i have found an incredible map and intend to stick with it for some time. thus, updating to a newer version of the pack i figure is out of the question if i dont want to start a new map. is this true? secondly, i notice when i log in to a new game it notifies me of a newer version of galacticraft. is it safe for me to update this or do i need to stay on the current version for tekkit to work? thanks.
