Sorry about the lack of recent updates. I have a lot of work related stuff on my plate right now, and will not be able to get much development done until September or October.
However, I did manage to fix the crashing squid problem (I hope) in this latest update.
The squid script was referencing a sound file, but sometimes that sound was not active for some reason, so it was looking for a sound that did not actually exist.
I think I have located all the places where this kind of problem might have happened, so the game should run more stable now.
