Of course I've sat down to play Brute Fort in the flesh for the first time with the freshly manufactured cards and... I've discovered a typo.
Fleet-Foot Boots
The card text for the top floor effect reads: "Trigger all other [on conquest] effects in this row or column"
It should actually be: "Trigger all other [on conquest] effects on this floor or in this column"
At some point during development 'row' terminology was dropped in favour of 'floor' which felt more thematic.
Instead of waiting for someone else to find this, I wanted to hold my hands up and admit my mistake. I think it stills makes sense in play, but it's really annoying (at least for me)!
