Unexplained crashes:

  • In two instances in M5, when Skinner and Willie start a conversation, the game crashed.
  • In one instance in M6, around the Simpson's house, the game crashed.

Real nice work there Nathan,Keep it up. I especially liked what you did with the wasps.
Trying it out right now; great job! :)
Hey guys, just a heads up that the mod can't save. It's a weird bug where the game can't create a folder with a colon in it (since the internal name has one). Once the download link is back up, the problem's fixed. In the mean time, don't make too much progress. Sorry for the inconvenience.
