Hello,

I meet this bug after updating my modpack :

Brief explanation of issue:
net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Router Reborn (routerreborn)
Caused by: java.lang.IllegalArgumentException: Duplicate id: barrel

Steps to reproduce:

Fresh profile with twitch launcher, add YeOldeTanks last version plus router reborn last version.

This error appears with the YeOldeTanks version 1.10.2-2.0.0, No problem with 1.8.0

Link to crash report/log in a gist:

YeOldeTanks version: 2.0.0 and 2.0.1

Minecraft version: 1.10.2 forge 12.18.3.2281 and 12.18.3.2254

I made a bug report to Router Reborn Author : https://bitbucket.org/zyberwax/main/issues/66/compatibility-incident-whit-yeoldtanks

i register the barrels using RouterReborn.MODID + ":" + "barrel" should not cause issues.
