So, probably within the next update mods won't work anymore, damn, this game (from the beginning) is tough, it requires a lot of time to grind and if you don't have strong characters (certain ones) you cannot enjoy the best content. I use mods for co-op, senkaimon and nightmare quests (never used on pvp, guild, epic).
I hope they just do some changes so mods can't be used uniquely on pvp, guild and epic but it can be used on the other modes.
As things seems to be running I think this is the end, thank you for the ride G-Bo :(
