Nothing in the log in the 3 previous seconds, so I'm not sure what triggered it.

I have the same issue too. Server regularly crashes due to this.
Here my full Server crashreport:

@Crusher565 your crash is about Caused by: java.lang.IllegalArgumentException: Can not set boolean field net.minecraft.entity.EntityLivingBase.field_70703_bu to java.lang.Float which seems unrelated to the original one. Check other issues or make a new ones for yours.

@LemADEC Looks like a projectile has lost its caster, probably because they logged out. I thought I'd caught all of these but apparently not, I'll look into it. Thanks for reporting.

@Crusher565 I've done a bit of digging and as I suspected, wizardry's involvement in that crash report is a complete coincidence (as you said yourself on cyberware's issue tracker, it happens regardless of whether wizardry is installed or not). This was a bug in Cyberware, which has apparently been fixed in the latest version, 0.2.10.15, so I suggest you update to that. Link to Cyberware issue, for reference: An-Sar/Cyberware#65
