Hi, Description of the steps and errors: As a GM, I can drag and drop Tokens into the playing field (Default Character tokens or simple Token not linked to Character). Those are seen in their default state by Players as expected. Token are movable and position is updated. As a GM I edit said Token, changing its name or any propriety (bar values, nameplate visibility,...). Token is updated as expected on my GM screen. PROBLEM 1 : My Players (or myself logged as a Player in another tab using specific option in cog menu) do not see the changes. Token seems frozen in a state. PROBLEM 2 : These Tokens are editable by everyone, exact same changes done by a simple Player (or me as a Player) are behaving totally as expected and update on GM or Player screens. PROBLEM 3 : Firebase.update method fail in console log (cf. end of this message for Log) throwing an Exception. This does not appear during normal test, only in console Log. EDIT : The bug started around 15:00 UTC, before that - and for sure from 12:00 to 14:00 UTC - Tokens updated as expected for everyone. Triage steps taken to try to solve: * Browser change : A fresh install of Chrome has been tested (I'm usually using Firefox), bug is the same. * Browser extension and addons: Fresh install of Chrome so nothing to do. Private session in Firefox without any addons activated: Bug is the same. * Clear cache Done, nothing changes Setup description Web Browser: Firefox and Chrome Browser Version: Last version 75.0 and 81.0.4044.129 Operating System: Windows 10 If Javascript is enabled Yes for Firefox, default parameters for Chrome Your anti-virus software: Windows default one List of any browser add-ons or extensions enabled: None in the last Firefox test, none as fresh install for Chrome Specific Log extract Log on Pastebin : <a href="https://pastebin.com/HiB12F6N" rel="nofollow">https://pastebin.com/HiB12F6N</a>
