So I have been modifying the probability of pineforest spawns during the day, especially the cowhead and mantis... They are pretty frequent, so I changed the probability down a few times all the way to 0.001 and still they are pretty frequent, for a low level player there are too many of them imo:
<entitygroup name="ZombiesPineForest">
<entity name="zombieCowhead" prob="0.001" />
<entity name="zombieMantis" prob="0.001" />
</entitygroup>
I then tried to change the frequency of spawning to no avail.
<append xpath="/spawning/biome[@name='pine_forest']">
<spawn maxcount="1" respawndelay="4" time="Day" entitygroup="ZombiesPineForest" />
</append>
What is going on?
