Sethbacon reports as a resident in Candyland that attacking silverfish causes more silverfish to spawn, but the additional silverfish caused by this will break blocks like wool even if stone reinforced.
This issue could allow DRO to be broken. Uncertain if this will be a feature or a bug with EE in Candyland since it does make the area more dangerous. However, the destruction of the end spawn could result in players endlessly falling to their deaths.
