Mupy-Mup!

The riddle of the century: my archers have an initiative of 12, and the Necropolis ballista has 11. The ballista goes first... I've searched through all the scripts, but I couldn't find any explanation for this...
Damn, I even cheated - I changed the arrival time of the ballista so that Greta from version 1.3 could at least somehow prepare, and it's still a painful experience...
This is a challenge. The developer says everything works and is passable.
