The Complete Rules of Tacticus, New Expanded Abridged Revised Pantshelm Edition, cannot all exist in the same space, or else odd quantum-mechanical effects will result in the removal of all dwarven beards in that space. We wouldn't want that, now would we?
Of course, that doesn't preclude a small amount of informal organization in which to experience the game, such as "unless the Complete Rules of Tacticus, New Expanded Revised Pantshelm Edition, instruct otherwise, the starter of the game is the one who keeps track of what the hell is going on for everyone else's benefit" or "once the starter of the game informs everyone what the hell went on the previous turn or other period of time-space-dwarfdom specified in the Complete Rules of Tacticus, New Expanded Revised Pantshelm Edition, everything else going on prior to that is what the hell is going on the next turn or other period of time-space-dwarfdom".
Of course, as seasoned Tacticus veterans, we know that the former is implied via Enid Butterclasped's Interpretation of rule 107.908.1 Section E, subtitled "Ordering of Events - Game Information - Periods of Required Drinking - The Score and Its Relation to Hoary Marmots", while the latter clearly follows from Appendix D-2 Section 77B, "Time Flows Forward, Unless It Flows Backwards Or Sideways & Considerations on Special Temporal Conditions Both Alcohol-Induced And Not". Sure, there is some debate regarding Enid Butterclasped's Interpretation and its ramifications on interior antman movements - heck, I think we all disagree with her stance that brewing occurs before the second subsidiary non-underground event phase - but her general thoughts seem logically sound.
