I am really new to roll 20 and dnd all together, but im really hoping this is not my fault haha. After i set my my sheet my group and i started our game. But whenever i try to roll anything, including a weapons roll or dex check or even init roll i get the following error. TypeError: Cannot read property 'substring' of undefined Is this a known issue and is there a fix for this? Can someone shed some light on this issue?
