Preface this by saying I know nothing about coding or scripting or the complexities of EfU/NwN. This could be a perfect example of "It aint Broke Dont fix it"
Would it be possible to have Raids have just a Quest Bubble in the end of the Raid when everyone is around, or a trigger, that when it grants Raid Xp it despawns after they leave? Or maybe a "Exit this Way" that locks it?
I've seen some of the Orc Raids linger with the "Everyone gets gold!" and "Everyone gets Supply" drops, which are excellent for those who attend but sorta open for exploit for someone to run in and grab free stuff.
Yes this probably needs to be addressed eventually, I'm sure not everyone is as honest and hunts them down to click the gold and potion clickies.
On the backlog.
