No error message makes it to the display.

In the console there is:

Critical error in __createPerchanceTree: TypeError: Cannot read properties of undefined (reading 'startsWith')

And in the error messages there’s just this:

Your generator's script seems to have errors in it. If you haven't recieved any other errors above this one which could indicate what went wrong, then this could be a bug in the Perchance engine. *etc...*

(“recieved” should be “received” by the way 😜)
