Is this normal?
01/11 08:46:57 [Info] Calling hook OnLootSpawn resulted in a conflict between the following plugins: MagicLoot - loot_barrel_2[4852702] (LootContainer), BetterLoot (True (Boolean))

Normal for you yes. Typically you wouldn't run two plugins that handle the same thing(loot). One or the other should be able to do both.
