You could just create "bug" gol yourself via the custom GoL feature. It was nothing impossible to create on your own. The problem is when it appeared out of nowhere, despite not being defined.

The ruleset was B12345678/S012345678/17, and you can make it pure white for good measure.

Yes it did. It caused a giant mass of rapidly expanding white GoL to appear across the whole screen. This is not intentional, and can happen on accident in many cases, including both known and unknown causes. I can't add an exception for your bomb because the fix I made applies to all possible causes of this glitched GoL appearing.
