I ran into an error message and circumstance that might interest you. The error was: Sandbox closed due to error. It happened with the Edge of the Empire Dice script in a weird way. On startup, the script checks all the characters for all the attributes that are used for the dice script, adding them if they are missing, and resetting certain ones of them if they are present. With no user interaction at all, the sandbox would crash with that error about 50-60 seconds after the initial character attribute check had finished. I tracked down and fixed what was causing the crash. It was doing a findObjs() call for each of the attributes for each of the characters, 2 characters at a time every 500ms. On the campaign I was looking at, there were 30 characters, resulting in 2280 calls to findObjs(). I changed it to just grab an array of all the attributes and filter it down to the ones of interest (only one findObjs() call now), and the problem has gone away. However, I was surprised that it would take almost a minute to crash and with such a generic error message. I thought it might be indicative of some other issue, with all those findObjs() calls some how leaving things in a bad state, possibly leaking some resource. I commented out all the manipulation in the rest of the script so that only the 2280 findObjs() calls were being made and still got the crash, so I don't think there would be any problems related to writing data. Anyway, thought you should know.
