So I am able to post certain background images and unable to drag any tokens or images from the token window. Even when I don't use these particular backgrounds, I cannot get any backgrounds/rubble from the menu. I have tried force-reloading (CTRL+F5) and have tried sending the background image to the very back layer. Nothing has worked. Using updated Chrome and Firefox, and the problem shows up in both. My players CAN see everything I put down, so it's going there. I cannot see any of it, not even when I try logging in on a different account.
