On game start. Unsure if this should be fixed by ramparnt instead, but i assume this mod does not remove the Arachnids force when moving them to biters, which confuses rampant. I'll report this on rampant fixed too.
The mod Rampant, fixed (1.7.5) caused a non-recoverable error.
Please report this error to the mod author.
