The ballista doesn't run out of ammunition, and this isn't a bug; it's just how it's displayed (as far as I remember, it's a glitch in the engine's encoding). This happens in all versions of the game and is allowed.

The ballista's window says it has 24 shots. With each shot, one bullet is deducted, and the count goes down to zero, then into the negatives. What do you mean when you talk about glitches in the engine's encoding? Are you saying that the fact that the ballista's window says it has 24 shots is a glitch in the engine's encoding? Maybe you're confusing the ballista with a catapult? In other versions of the game besides the 3rd and 5th, I don't think there are any siege weapons. Am I wrong, or are you?

P.S. The organizers also need to take care of their family lives, and half of Saturday is usually spent at markets/stores. So, you shouldn't nag them too often about them not being around... just wait a little; we're trying to respond quickly.

I have nothing against this and I'm not nagging, I'm just saying this in relation to the accuracy of writing the rules and compiling the list of bugs, so that you, the organizers, have more free time later.
