Inside the game folder" \www\data" is the .json "Map364.json" (you can search for it). Open the .json with Notepad or any similar text editor. Use the search or find function (Ctrl + f) of the program and search for "you helped out" (without the quotes). There should be only one result. When you jump to the result, it should look like this:
"parameters":["you helped out it' s only fair you get to"]},
Notice the space between the apostrophe ' and the "s"? That is the tab key input ("\u0009"), an unsupported character that can crash the game when it tries to load the file. You need to remove that.
To make it easier, delete the part that says "it' s only" and replace it with "it's only". This should fix the issue.
Hope that helps!
