Non-hostile Sirines at Lighthouse area while resting

Tangente

Is it broadly known that non-hostile Sirines are appearing while resting at Lighthouse area? Is it a bug or feature? Because I am able to kill them with 1 level solo character using the "hello cheese" and in about 1 hour I am able to achieve max level. The "hello cheese" means you initiate dialog with NPC, then attack him/her and then again initiate dialog, attack, et cetera. He or she will never turn hostile on you. With Berseker, Barbarian or Elf it is even easier because their are somewhat immune to charm and you don't need to "hello" them.

Nifty. Hadn't heard that one before. XP is not hard to come by in BG, but this would be a convenient grind for bringing along a late dualing Imoen, for instance.

This is a bug and has been fixed internally. It will very likely be in the next patch.

Well, then I should start looking for a new speed running trick. But even if they appear hostile its quite good for some leveling from midgame to lategame. 2000 XP is a lot.
