The curious part here is that they work in some games but not others, indicating that the problem probably lies somewhere in the game, which might be exceedingly large, leading to a timeout, or you might already have characters in your journal tab with those names. In the latter case, dragging from the Compendium would only drag a copy of whatever you have in your game instead of fresh from the Compendium. (This is the desired behavior, since you may have made custom changes or provided a different icon, for instance. In the problem game, make sure you have removed any existing character that might have the same name as the one you are trying to drag in, and then see if you still get the same problem when you drag in a fresh one. If you do still have the same problem, then the issue is probably a bit more involved. In this case, please carefully work through these steps of our guide to Solving Technical Issues : Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions. Step 3: Clear your cache If none of the above succeeds, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) This last step is the most important, as it provides behind the scenes insight to the devs. Thank you!
