This failure was being triggered due to the browser refreshing when too many ThreeNodes are created (see here for more info). Reserving a single dialog node in the BAMView restricts the sim to build only one ThreeNode.

The above commit should have solved this.

Can you confirm this isn't happening in this dev version @KatieWoe?

Looks good in the dev version
