Was it in the regular turn, not the artillery phase at the start of the AI player's turn though?

If it was in the regular course of play, it was direct area fire (Z fire) and not indirect.

If it was in the artillery fire phase - something needs debugging (if it can be persuaded to do it regularly, one cannot really debug 1 in a 10000 events that easily!). Or something might be wrong with the tank data, unit class wrong, etc.

So was it arty fired in that phase of the AI turn, or an impromptu Z-fire in the normal turn?. It would be handy to know precisely which.
