Dynamic Lighting mark-up : is there a maximum amount per page?

I'm in the process of putting a lot of dynamic mark-up lines into a single page, which hold 15 separate smaller maps as part of a single tower. After marking up about 75% of this map, and new mark-up I add now appears to draw to BOTH the Dynamic Lighting Layer AND the Map layer. These two images show this. The first is the Dynamic Layer, the second is the Map Layer, with the room top/right side showing the mark-up on both layers. I deleted this and it deleted from both the dynamic and map layers. (ignore the pink circle on the GM Layer on the bottom left, which shows up regardless of what layer is selected). Anyone else had this problem?

That is really peculiar. Are you drawing all of these with the freehand tool?

Pink is one of the colors I have made note to never use in the DL layer due to api scripts using it, are you using a session with api scripts enabled?

Yup - all the pink lines are done freehand. And no, no scripts running. Just Roll20's standard tools and nothing more.

Hmm. Freehand wasn't permitted on the DL page for a long time for efficiency reasons.  They made improvements, but that is quite a bit of it.  If you were a Pro Subscriber, I might be able to redraw those as simplified poly-lines with an API script, but as it stands, I think I would suggest copying the map and redrawing it with poly-lines. You might want to preserve the broken page and file a ticket to see if there's a bug that can be fixed by the Roll20 Devs. 

Thanks - I’ll give that a try.
