I’m haveing an issue with reactor, setting the mass amount. After setting the amount, the amount on the part doesn’t change. I can click on the part again and it still has the same setting I was trying to change. I have to set the amount and hit the arrow button to lock it in. Then it increase my setting by the one click and the arrow button down jumps past the number I set and the arrow up jumps past it the other way. Is this something spacific to my machine or is it a problem that other have had?
