Hi, (sorry if my english is not good) I just set my PEX to add new groups to my server. When I finally finish to edit, I had a really big problem: when anyone switch from PVP world to PVE world his/her PVE inventory is replaced for PVP one. I tried to check per word inventory config, but I couldn't find any parameter associated. I have installed another plugins that they can be the problem, so this is the list: - AntiCheatPlus - Clear Lag - Core Protect - Essentials X & Essentials Chat - Hats - Holographic Display - Lockette - Login System Pro - Multiverse Core & Multiverse Portals - OldCombatMechanics - PerWorldPlugins & perWorldInventory - PermissionsEX - Skin Restorer - Survival Games - Vault - WorldEdit - WorldGuard I checked as well Essentials and PEX config, but I couldn't find anything that notice me where is the problem. I hope you can help me. Thanks!
