I'm having poblem with "Killer Joe", it kills some mobs and drop a sword on the ground

• EnderIO:EnderIO-1.7.10-2.3.0.429_beta
• EnderCore:EnderCore-1.7.10-0.2.0.39_beta
• Minecraft:1.7.10
• Forge:Forge 10.13.4.1566-1.7.10
• Optifine:OptiFine_1.7.10_HD_U_E7

What happend?

Our last 1.7.10 release was 4 years ago...

However, the Killer Joe doesn't (and never has) had code to drop anything to the ground. So some other mod is removing the sword.

Ok, Thanks.
