Verbose logging was turned on. I don't have the KSP_x64_Data\output_log.txt, I'm assuming that is for an older version of KSP.
Environment: I cleared out all my mods except for precise node, click through, and toolbar control to get a pure testbed, started a new sandbox game, and repeated the issue. Tested with clicking through one to deselect the node, and quicker clicking to deselect the target.
