LOS strange behaviour


I,m testing a LOS with persistence to always,visible to always and draw range enabled.
I want to draw the LOS and then keeping it in the map until I click on LOS thread button again.
So I draw the line cliking and drawing. OK now the thread is visible but when I click another point in the map the LOS line change.

Is it a bug? How can I keep the line in the map until i click on LOS button again?


I’ve recently been working with a miniatures game and a friend suggested I use the LOS string as a ruler. It does work fine at 100% zoom. At any other zoom level (lower or higher) I am experiencing the same problem. The end points of the thread line move to different positions. Try and use the thread at 100% zoom specifically and see if it behaves ok.
