Adding some clarity. I'm a player in Ravenknight's campaign and this error occurs not when a particular script is used but on seemingly random occasions. For example, A macro that has been used flawlessly on multiple occasions during an evening suddenly produces this error. Even after restarting the API several times it still occurs and only after some time has passed (sometimes minutes, sometimes hours) does the restart remove the problem. It's not linked to a particular token in the game, or a particular macro, or a player. It doesn't seem linked to a particular script, nor does it happen during controlled testing. Ravenknight's copied the campaign and cleansed it from unused information in order to ease the burden for the server, but that didn't fix the issue. The only similarity between the crashes, is that they happen when a macro is used. It's a fairly rare occurrence as it only happens a few times per game night, but it completely breaks the game as well as the mood for players and GM alike. Please advice.
