LoS line definitions not showing on map

[Valdemar]

I am defining line of sight on a map for Tegel Manor (pretty big detailed map). I am about 80% through, and the lines are no longer showing up when I drop them. It is apparent from some terrain items that they lines are there, but they are not showing on the map - makes it really difficult to finish as I cant see what is there or not.

HELP!

Example of defined item that lines are not showing

No Extensions loaded.

The issue is not limited to terrain at this point - any new lines I put down show up while I am dropping them but instantly disappear upon clicking. I have tired walls, doors, windows, terrain.

Thank you for your help.

You mean in your third image you do not see the LOS lines? That is because you are in Play mode. See the die is clicked in the image control? Click on the LOS icon instead in the top row.

The terrain you can see is there is not showing the occluder line definition in the second image - but it should be visible in the second image (green lines and points...

To clarify - I included the third image to illustrate that the terrain definition is actually there - but not visible when in LoS definition mode.

The first image was just to illustrate that there is a bunch of stuff already defined, just handling the outlying areas and terrain.

You have a couple of blank layers. What are they for?

I can't diagnose an issue from your screenshots. I assume also that you are doing this all in the same campaign?

I'm not sure what you mean by blank layers - yes this is all in the same campaign

You map has 3 layers, two of them have no names, both of those have associated LOS with them, and one of them is locked.

I've never put LOS on more than 1 layer. Is it some how related to the unnamed layers or having more than 1 LOS layer?

That seems to be the issue - I guess I had somehow added a second line of site layer. Is there a way to merge the two LoS layers - if not no bid about 80% of what I have done is on one of them, I could just redraw the part on the second layer if needed...

I think you are supposed to be able to have multiple LOS layers I just don't know. Not sure if one of Mr Z's videos addresses this. Hopefully he can point us to the solution as I would like to know more about this too.

I had inadvertently added a second LoS definition layer - my bad.

However after starting to enter the items I had on the second layer into the first (deleted the second layer) it started to do the same thing on the first after adding several lines and points. Is there a maximum number of lines/points you can have on a layer? After drawing a line on the LoS layer now - the line draws and the points add, then immediately the line disappears from view (I suspect it is still actually there - just not showing on screen.

So question - Is there a maximum number of lines / points that you can have on a single layer?
