Hi GM Sean, It sounds like this might be a case of needing to clear the Chat Archive (note: not clear your current Chat Log ). A GM might want to copy/back up the Chat Archive before the Creator clears it. Just in case though, I have copied your post over to the thread dedicated to problems with Tomb of Annihilation , where it will get higher visibility by the devs, and other users who have experience running the module. Since you can follow the progress there, I'll go ahead and close this thread. Please feel free to open a new issue if you run into any other difficulties.
