Error on 2nd level (level Y) of Runouw's "Last Legacy" flashgame when attempting to perform Delta (an in-game action that is meant to make textures less saturated, slow down in-game time similar to SuperHot, and edit tiles) on the second Delta Orb.

Educated guess: this is maybe either a regression or a platform issue because this level worked a few years ago. The only difference then is that the browser/Ruffle is newer (duh) and that I am playing on Linux Firefox instead of Windows 10 Firefox.
