[Medieval Warfare: DTE] Encourage players to actually make cannons/defend

[fixitqixit]

Map name

Medieval Warfare: DTE not to be confused with the regular map

Is your feature request related to a problem?

Yes, in ways. Instead of players making cannons and defending which I believe was the original intention of this DTE version of the map. Players instead of doing this rush to the centre barrier of the map (made of glass) and begin constructing sky bridges which I think confuses the dynamics of this map.

Describe the solution you'd like

Blocks that are placed in the void before the glass barrier comes down (through monument modes) are either subject to the falling blocks module or are completely disallowed (which probably will be better as a deny message can be given to players).
