test check points not working

[PietrOZ]

I'm working on a complex mission and I have to keep changing  the objectives because they don't work as they should, the problem is that when I modify something and then  try to test the mission from the previous checkpoint it doesn't let me, there's a big yellow "!" just lef to the checkpoint... why? it's very tedious having to restart each time from the beggining...

Those Checkpoints get "dirty" if the mission is changed around them. Afaik it depends on wheter you changed anything that matters in the timeframe of those checkpoints.

What do you mean with "in the timeframe"?

This is an example: mission is to launche and dock 2 vessels, I set up the check if docked, vessels dock and nothing happens, modify the node, and have to restar from the first launch...
