Hi !
I have a problem.
I fought the slavers in the Copper Coronet and now Joluv the merchant is always in red mode, constently fleeing me.
How to fix this pls

How on earth did you manage that? Never mind. Unless you know how to safely edit saved games in Near Infinity your only option is to go back to a save prior to the fight, and keep it away from Joluv's area. Also do not use hostile area of effect spells.

Hmmm, maybe a "Charm" spell works, temporary? Idk he he will sell things in that state, though...

Thank you for your answers.
I had to reload an very old save but i dont have the problem anymore.
Maybe i killed an innocent inside the inn.

Unfortunately, in BG2 you can't talk to charmed characters (unless the EE changed that).

The only thing I can think of is friendly fire. Keep in mind that most AoE mage spells would also hit non hostile targets.
