Bug? strange travel movements at 'optimized' path

[Inschenieur]

Hey everyone,

when I select the processes 'W 2mm Bot(1)' and 'W 2mm Mid(1)' and start printing, then I get these random seeming travel movements which you can see on the attached picture. These movements happen when the extruder switches from inner to outer perimeter and ignore the 'avoid crossing outline' option. The problem arises from the 'optimize start point for fastest printing speed' option (when I set it to 'choose closest location to ...' they don´t show up.). As a matter of fact it is obviously impossible that it is faster to travel around the letter and start printing somewhere else instead of just keeping going if it's just a single contour. Is there any way to fix that or is it a known bug?

Thanks for your help!
