Issue's been fixed as far as I can tell now, all games that I'd had affected are now functional again. Many people have posted about their game chats no longer being usable - entries disappearing, rolls not showing but only for them. I'm also experiencing the issue and would like to share what I've learned so far: The issue seems centered around sheet macros corrupting the chat archive. Clearing the chat archive will let you roll again, but if the macro doesn't get fixed, you'll have to keep clearing the chat archive every time it gets broken by the character sheet again. Here's a video of me forcing the issue in a completely fresh game with no API additions: <a href="https://www.youtube.com/watch?v=SrioFxRvQ7M" rel="nofollow">https://www.youtube.com/watch?v=SrioFxRvQ7M</a> Here's images of comparisons for where the chat "breaks off" In two separate campaigns, nonetheless - one of which wasn't even being played at the time where I encountered the bug. When we last played, there was no issue, but on opening the campaign to check today, the bug was apparent for me. An example of the repeated text spam per roll that was somewhat humorous: Here's the specs with which I initially tested: (it's 2 am - I turned all my addons back on once I figured out what seemed to be going on, so they're visible within posted images/videos) Windows 10 Pro 10.0.19042 Build 19042 Chrome Version 90.0.444.30.212 Official - 64 bit & Firefox Version 88.0.1 - 64 bit All addons disabled. All antivirus disabled. Attempted before and after PC restart. That's all the free Q&A/bugtesting I'm up for tonight, however, so hopefully this helps anyone understand the issues they're having a bit more and helps the devs figure out how to repair the issue. Cheers.
