ToME: the Tales of Maj'Eyal

I'm not sure what happened...it seems like after I use shadow simulacrum on an enemy adventurer, and the copy killed the original, I accidentally bumped into it...the game registered that as attack, and it killed me...isn't it supposed to be friendly?...after I got out of Eidolon plane...the one's that supposed to be the copy turned into the real full enemy...

Log attached...

Also the newly created simulacrum after this will be hostile too...I think....at least it has red border...
