Crash Log

Player said that they had some Ice & Fire mobs being spawned by their woot factory, not sure which of them is causing this.

woot-1.16.3-1.0.0.0
forge 34.1.25

Edit: Update to the issue, seems to be all of myrmex from Ice & Fire

As a stop-gap until I work out what is going on with the Myrmex mobs (looks like I am failing to get the health of the mob from Ice and Fire - I think), then you can blacklist the particular mob(s) or the complete mod in the config file.

Complete mod
[policy.blacklist] captureMod = ["botania", "iceandfire"]

Specific mobs
[policy.blacklist] captureEntity: [ "iceandfire:xxx". "iceandfire:xxx2" ]

I've added an extra check health lookup failures which don't seem to work with the Myremex mobs. This is available in 1.0.0.2.

Finally tracked down what was going on with Ice & Fire.
The Myrmex mobs cause an exception when EntityType.loadEntityAndExecute is called.

I'll test the rest of the mobs in Ice & Fire, but I think it is just the Myrmex that are the issue, so I'll internally blacklist them.
