All the authors of the Skins recommend not to make cocktails and I stick to their recommendations, in this way they cannot reply that the fault is mine.
Each zip file is optimized to work with its own Skin, if you want to use Alain's icons just carry those icons into the new speedcam.zip.
I made the tests strictly with the original material.

In the latest Skins the reports of the Speedcams work badly, the update of 21-05-2020 works better but only if the Big Speedcam is not activated, in the others it works badly even with the Big Speedcam disabled.

To do the test just create a txt file with Spudigo with a category positioned every 500-600 meters on a route around home.

The same problem also exists in Luna's Skin.
