TypeError: Cannot read properties of undefined (reading 'length') (at "Terminal")

How did this happen?

I had an error and now I cannot open the game. Honestly, I have no idea on what caused this error. I'm just submitting it in case anyone may have a similar issue, so we can prioritize bug fix, or to help identifying the bug, by common patterns.

Update: I restarted the game. Somehow, now it works. Bug is gone. I still have no clue what just happened.

I can think of some ways this can happen. If you have a bug in one of your scripts such that you end up redefining one of the fundamental js objects like "String" for instance. We put in protections for String and Object, but there are surely others that are still capable of crashing the game if you set them to undefined. Ah, JavaScript...

If it happens again and you can narrow it down to running one of your scripts, please post the script.

This is now a (less detailed) duplicate of bug #1482 "[BUG] Game broke on terminal history search - TypeError: Cannot read properties of undefined (reading 'length') (at "Terminal")".

As such, this issue should probably be closed.

Good catch. I will close as dupe for now, but it's good to recognize that this has been reported twice (and this probably happened more than twice)
