LEGO

If memory serves that particular brown in recent manufacturing from Lego was known by the public over some time to have embrittlement issues, so probably not something you did to it, but something as of now that Lego has fixed on their end if you pick up that brown from a current set or from their stores.

Box of shame or hall of Fame, you decide where to hang this bricks frame

Damn. First time I've seen a separator both fail and succeed simultaneously.

Get the torch. It can’t be stuck if it’s liquid

You found a worthy contender to fight a Nokia.

There are such things as brick separators?! Why hasn't anyone told me, my fingernails could have been spared such anguish.

The old "Reddish Brown" as of three or more years ago is know to be brittle. LEGO has changed to formula since which apparently fixed that.

Apart from your problem of getting the remains out, just contact LEGO support for free replacement parts, as this is a known and accepted issue. Keep the parts, though, if you ask for a larger number of parts, they might want the broken pieces back as proof (theoretically, I have nor heard of such a case personally).

Maybe that’s what the warning glyph was trying to warn you about.

Where is your God now!?

As a child of the late 70s/ early 80s, we never had brick separators. The majority of my bricks had teeth marks! 😁

Those fucking brown pieces
