Sometimes when I am laying down a long string of dots around a bunch of dungeon walls, I miss a spot where in a long wall I missed putting in dots for a door or something. A month ago, I was able to select a dot in the middle of that line and click the pen. The code would then let me add any number of points between the selected point and the previous one. Now, the default start point is always the last point in the line, so I sometimes have to delete 20-30 points or more to get back to the spot I missed and then re-do it all.
Hi @mikebnova and welcome back to the forums!
Please bug report this! I believe it is a break caused by the recent update to editing Dynamic Lighting and not a removed feature.
