After running continuously for several weeks, my emulator script halted with this error:

A Simple Sun-Earth-Moon emulator.: 0.3 [script:Sun-Earth-Moon demo] Script run-time error

Failed to perform mandatory yield

lua_script:159 function emulation_step

[C] function _tick

[C] function timer_event_wrapper

[C] function _handleEvent

The script, or an earlier version thereof, has halted similarly on at least two previous occasions. This, however, is the first time I've been on Sim when the crash occurred to receive the error message.

The instance of the object that crashed is at https://maps.secondlife.com/secondlife/Builders%20Brewery%20Sandbox/36/69/498 Anyone may take a full perms copy. I have not reset the script.
