Map Editor Bugs

Hi,

happens that at least once every 45 minutes of work, the map editor closes instantly making me waste time and work. I attach two logfiles.

I hope you can solve these problems.

logfile_editor (2).txt

logfile_editor.txt

I simply cut a spline, eliminated the extra piece of the mentioned spline, and tried to attack a new one (always the same type curbstone_0_15x15)
