This usually happens when there are several copies of C2 running on PC. Check task manager, try turning it off and on again
Unfortunately everything I tried related to that didn't work, such as closing and reopening both C2 and the Chrome browser, as well as checking Task Manager to ensure there are no extra copies of C2 or Chrome open. Another possible way around my issue: Is it possible to find some sort of Chrome data file that contains the Local Storage keys related to localhost:50000, and copy them, and replace a "50000" with "50002", so that the same set keys are available on 50002?
