I have several map pages that I have already built. Now I can't add or remove anything from them. I can move the existing things around oddly enough. I am logged in as the DM and I've gone into all the layers and tried it, since I have items in all the layers already. I've tried logging out and back in, logging in as a player and then back to a DM, restarting my computer, updating chrome. I'm thinking it's some setting in Roll20 I don't know about? Any help would be greatly appreciated!!
