Atomic Science no longer crashes the game but causes some annoying issues. Atomic Science results in the inability to craft essential pieces of equipment like heavy duty plating among other things. It also makes it so copper and tin ore cannot be smelted, and must first be broken down into dust before being able to be smelted. This has been an issue since build 653 and I was really hoping it would be fixed by now.
