I am not sure,if you mean to change only tne first row or more.
now i changed it to this :
<biome name="wasteland">
<spawn maxcount="2" respawndelay="0.001" time="Day" entitygroup="ZombiesWasteland" notags="commercial,industrial,downtown" />
<spawn maxcount="2" respawndelay="0.001" time="Night" entitygroup="ZombiesWastelandNight" notags="commercial,industrial,downtown" />
<spawn maxcount="4" respawndelay="0.033" time="Day" entitygroup="ZombiesWasteland" tags="commercial,industrial" notags="downtown" />
<spawn maxcount="4" respawndelay="0.002" time="Night" entitygroup="ZombiesWastelandNight" tags="commercial,industrial" notags="downtown" />
<spawn maxcount="4" respawndelay="0.0167" time="Day" entitygroup="ZombiesWastelandDowntown" tags="downtown" />
<spawn maxcount="4" respawndelay="0.002" time="Night" entitygroup="ZombiesWastelandDowntown" tags="downtown" />
<spawn maxcount="1" respawndelay="0.3" time="Any" entitygroup="EnemyAnimalsWasteland" spawnDeadChance="0" />
<spawn maxcount="1" respawndelay="1" time="Night" entitygroup="ZombiesWastelandNightHard"><!--Element appended by: "Snufkin Custom Zombies PLUS"--></spawn>
</biome>
but still,they say the wasteland is most empty of z´s -.-
my Server Values are :
MaxSpawnedZombies : 64
MaxSpawnedAnimals : 50
Its a 10 Slot Server,and most Time there are 3-5 Player online,in Case that it matters...
If you have maybe one more Hint for me ?
