Bizarre. There is clearly something odd going on in my Mafia then. You can see from the screenshot that it's telling me differently to what it's telling you. What is particularly strange is that it isn't just not updating the data of a Mech, which does have 120 ML, as the previous encounter was a Quiet Healer.
And the same test as Veracity shows :
> ash monster_defense( $monster[ burly ] )
Returned: 108
> ash monster_attack( $monster[ burly ] )
Returned: 120
Update : Created a new mafia folder, put 10572 Jar in it, ran Jar, shut down Mafia, copied settings directory from my old mafia folder, but nothing else, logged in as same character, still shows attack of Burly Sidekick as 120. Same in 10578. Deleted sessions directory and tried again, same result. What else can I try ?
