Bugfix: deco planner did not initialize properly Redoing a deco calculation in the planner, after a change in used gasses, did result in wrong gas usage figures. And a restart after sleep made things right again. This all feels like some initialization problem. Nothing very important as it's only a desktop planner, but a bug it is. Code reading, I found the not correctly initialized data. Reported-by: Teun (forum user tdewilt2) Signed-off-by: Jan Mulder <jan@jlmulder.nl>
