Implemented Turret Counter on HUD in preparation for Turret Count Limiting (clamping how many Turrets can be built in an area on servers, to dramatically improve server performance).
Added "Heavy Turret", which packs approximately 4 times the power of a regular Turret and has faster tracking, but uses 4 Ammo per shot. On Official Servers, in preparation for ultimately limiting all Turrets to 100 within a 10,000 unit range, only 100 Heavy Turrets can be placed in a 10000 unit range, including ALL Auto Turrets & Plant Turrets within that range.
Imprinting intervals increased from 4hrs to 8hrs between each imprint. Each imprint gives a large amount of imprint bonus per imprinting.
