The most detailed steps I have are to have two people fight one another, have another join and see where they spawn (if they do) and then have more join (while the first or second is still on the spawn) - all being done right, when someone moves off the spawn, the turn bug may come into effect.

While I don't think it's consistent, I've only ever seen the turn bug occur in circumstances where someone has covered the spawn of someone, disallowing their presence on the battle for a little.

This might say that the bug can be fixed by making it so standing on a specific spot on the battlefield DOESN'T put joining combatants in the void until you move, but it has never been a bug I've seen someone produce consistently.
