I've been writing this Twine for about 24 hours without any issues. Now, after having a lot of (mouseover-append)s in the first two pages, the Twine always crashes and gives this error message when I try to play the third one. I thought maybe it was an issue with my stylesheet so I removed it entirely but still get the same error.
I'm not using any Javascript. I will post the error messages and the code to my game in a second. (Using Harlowe) I got the same error on Windows version but the words are cut off.
I just removed all the (mouseover-append)s from the section that was breaking and now it works...not sure why it crashes, though. Does using too many mouseover-appends lead to crashes?
