Not completely sure if this is due to realistic progression or not, but I do not have the capability to use maneuver nodes after circularizing. I have already upgraded the Tracking station and Mission control to level 2. I have noticed that I have the ability to place a maneuver node while I am ascending, but once I circularize or get close to doing so, the opportunity to place a node is no longer available. As soon as I reach orbit, my orbital line changes from the typical single blue line from vanilla KSP to three pink lines with one of those pink lines actually showing my spacecraft travel direction. Anyone know what the problem could be?
I'm new to the forums and could post a screenshot, but I'm not exactly sure how to add an image to a post haha.
