Hi! I love Bitsy. I noticed a freezing bug when working on a game, and thought I should report it here. Apologies if this is already documented -- I searched the 4.0 thread for 'freeze' and didn't see mention of it there.

Version: 4.5

Tested in: Firefox 50.0.1 (64-bit), Chromium 63.0.3239.108, both running on Fedora 27

Issue: Exits pointing to uninitialized rooms will cause the game to freeze. It appears that under certain circumstances, these exits can be introduced to game data when deleting rooms.

Steps to duplicate the issue from a new Bitsy file:

* Create a new room, so that you have Room 0 and Room 1.

* Place two exits from Room 0 to Room 1. There will be two exits in the Bitsy data for Room 0:

EXT 0,0 1 0,0

EXT 1,0 1 1,0

* Delete Room 1. One exit remains from Room 0 to Room 1. This exit is not visible in the editor, but it can be clicked on with the mouse and the 'Exits' panel will react.

EXT 1,0 1 1,0

* Stepping on this exit will freeze the game.

really great bug! thanks for writing this up

I'm adding all these old bugs to my github backlog so that I will get around to actually fixing them soon
