Update: I researched this because I remembered a Bug report from the past. This has been reported twice, that I could find, and neither thread resolved to a cause or solution being reported. It's not clear yet how to reproduce the issue consistently. Past threads, <a href="https://app.roll20.net/forum/search?q=shadow%20tok" rel="nofollow">https://app.roll20.net/forum/search?q=shadow%20tok</a>... Want to try the troubleshooting triage for diagnosis, Ravenknight? If so I will repost the steps to take here, leading to possibly getting a Console Log that could help the Devs.
