Bug? Players can't see Painting layer
FGU, 5e, DM.
In the last game, the players were unable to see the contents of a particular painting layer on their map. Layer visibility was set to "All" in Image Control and I could see it in Player Preview. They were able to see the painting layer immediately above it in the layer stack. Cycling through the layer visibility settings restored the image.
If it's relevant, both layers were similar images - masses of cobwebs applied as stamps - but the layer which was properly visible was drawn before the recent upgrades to Image control, and the layer which was initially invisible was added to the map post-upgrade.
