ncreased harvest rate
made armor and building speed same as inf & veh.
harvester harvests faster, unload takes 10s
made armor and bldg queues same speed as inf/veh.
changed inf. speed; veh. sight
infantry get 100% on rock, 90% on sand. Suitable since d2k is big and open
and infantry move slow (80% is bad for sand).
Vehicle sight range for siege tank, rocket launcher, mcv set to 8.
Infantry sight range set to 6. (their weapon range is 5; openra renders
sight range too small)
changed crate money distro, unit odds.
money can now come in $500, $750, $1000 or rarely $1500.
50/50 chance of  getting a money crate or a unit crate
Crates designed to show up often but max 2 on map at once. Lifetime 2
mins.

removals:
crates with unit promotions removed
explosive crates removed
reveal-map and hide-map removed, as soon to be obsolete.
MCV currently turned off, until delay implemented (I would recommend 10
minutes before you can get mcv in crate).
