Spawn Cap unreliable.

[DEX47]

I have my "Spawn Cap" settings below average: 90 total. How did my map spawn over 450 in an area? I must prevent this from happening. How do I enforce Spawn Caps to be true to their value? Is there a despawn enforcement to prevent this? Are Spawn Caps bugged?

15 Ambient
10 Creature
30 Monster
10 Opensky
10 Underground
15 Watercreature

90 Total

There's a few things you can do to help locate the problem

Check that JAS has spawned the all of those entities (many mods have their own spawners that need to be turned off in their respective configs. Lycanites and Mo'Creatures are just 2 examples).
-JAS commands are one useful tool (unless you used /jas killall or /jas countcap to get your figure of 450)
-turn on logging in LoggingProperties.cfg

If that IDs JAS as the culprit, please paste links to logs and configs.

If JAS isn't spawning the extras, it could be many things. If you've already checked other mods' spawners, then check to see if there's a particular type of entity or CreatureType that's spawning more than others. Does it spawn like that without JAS?

Lastly, check GlobalProperties.cfg. Are the VANILLA COMPATABILITY settings default?
(ie "Turn gamerule spawning off on start": false,
"Empty vanilla spawnlists": true,
"Disable Vanilla Chunk Spawning": true,)

[DEX47]

Will /jas killall remove all or my Custom NPCs?

[DEX47]

I eliminated the additional spawning from Mo'Creatures. Vanilla spawning doesn't seem to be doing anything on it's own so I have the CustomSpawn from JAS enabled and vanilla disabled. However I have run into an old issue that caused me to remove JAS before. I am hoping it is a config issue that will resolve things.

I have fish spawning on the ground and inside the ground. Note that I do have Aquatic Abyss mod and that doesn't seem to blend with JAS fully. I finally got the sea serpents to spawn but the don't do so in water. I also have a critical error that crashes my server at times until I remove an entity with NBTexploter. These entities have always been fish spawning with errors. See Crash log below.
