Treasure Chest in PoM forest bugs

[Vaarsuvius]

Hi,

I'd like to report a couple bugs about the Treasure Chest NPC that spawns in PoM forest (the one surrounded by 4 halflings)

It's an enchanter mob that uses Theft of thoughts, Tashania, Curse of the Simple Mind, Gravity Flux, Gasping Embrace, Incapacitate, Discordant Mind, Shiftless Deeds, and last but not least Allure
According to the wiki, Allure only enables to charm creatures up to level 51. So how can it charm a lvl 58 player ?

On the one hand, I've noticed a few times already that as soon as it manages to charm me (58 necro), all the DoTs I had managed to land on it would fade right away. Even those that may have landed on it a few seconds earlier.
But on the other hand, any debuff or DoT it may have landed on me would NOT fade when I get charmed.
Is it how things are supposed to work ?

Could you have a look at those issues please ?

Thanks in advance
