So I've just recently started using Roll20, and I am currently having a major issue. When I try to start a campaign with the crows rest pack I get this "Upgrade in progress: we are doing a little spring cleaning to optimize your campaign. please wait... Please do not press the back button or close the page." The bar below the words is entirely green, and it keeps refreshing. I am not really sure what to do, I have disabled my adblocker and even signed out and back in again, restarted my computer, made sure java was up to date. I do not have this problem when I just start a new campaign with no helpful pack. I am all out of ideas, if someone could help it would be greatly appreciated.
