I have a bug with the game. That is caused by the ohscrap/scrapyard mods. My delta v is halved in the stages. This causes me a great inconvenience. And makes maneuver nodes not work. Here is an image of a spacecraft that should have about 700 delta v, but only shows it as 305. Kerbal engineer shows the correct amount. But doesn't integrate with the in-game maneuver system. Is this a problem with my computer or the mod itself?
