Carbon steel pan - rough surface. Fail?

Thanks!
Sorry, the pan is almost black and I couldn’t get an angle on it to photograph the rough area.
I thought if the seasoning reacted to an acid it would melt, not ‘gator.’ The crepes I re-heated showed no dark/scorch marks but I hear you, something must have scorched and stuck.
If I’d taken the scrubby to it I wouldn’t be bothering HOs.

Will now attempt to remove my claws from the ceiling tiles.
