Help - Game crash when re-entering room

I'm very far along in a "point and click" adventure/puzzle game and for some reason my game is crashing when I enter the latest room I've created.

There's nothing special going on in the room. No scripts. No sprites. Nothing except world tiles and a single item tile with the following script:

on collect do
swap "grass"

Here's what's happening:

As you can see, I can start in the new room, but if I leave and come back, the game crashes.

The room I exit to (with the trees) also has no script. I've changed nothing in my player or game scripts that would have affected these rooms or anything within them. I've even swapped every tile for "white" and it still crashes. I'm at a loss.

The only thing I can think of is I've reached some kind of memory/storage limit within Pulp?? Idk.

Any help would be greatly appreciated. I'm so close to finishing this game and I can't wait to share it!

What does the browser console say?

Okay, so I deleted the room edge exit on the room with trees and re-added it and the game no longer crashes. Must have been some weird glitch with the exit.
