Hi guys,In case you missed our announcement of what will be happening to game saves in 0.7.4 - you can read about it here:But in summary -- the introduction of Creative Mode and an overhauled game save system means that older saves will no longer be compatible with future versions of TerraTech.We do our best to avoid having a backwards compatibility issue like this (our last was back in September 2015) - but sometimes it's a necessity with big overhauls like this. It's a common occurance in most Early Access titles.However, we do have version 0.7.3 available on Steam for those of you that wish to carry on with your older saves. To gain access to that branch, you can follow the instructions in this video -Let us know if you are having any trouble with this and we shall lend a helping handThanks!
