Tweak made to fort destruction (as outputted)

[Kaz]

I've made a quick tweak mid-age.

Basically it shouldn't really change anything as far as the back-end goes, and what actually happens when attacking.

However, instead of telling you that hardly any forts were destroyed (even if some were) then it'll now tell you that forts were actually destroyed.

e.g. Aeyliea recently reported that 0 forts had been destroyed on an ease hit, when actually 150ish had been destroyed, and debited from the target, just not reported in the post-attack news.

You still might find it says hardly any forts went down, but at least now that should be an actual reflection on what happened, rather than a display output bug
