Just read this steam post and it sounds bizarre. Can anyone confirm this?
It's confirmed. Looks like a restart.
No. It is only a display thing, it seems. You still get the same old XP by the looks of things. Just the display is glitched.
It's NOT only a display thing.
"Only active companions receive experience" OFF means that the XP is shared between ALL the companions you have (which means the active party and the guys sitting in the capital).
"Only active companions receive experience" ON means that the XP is shared only between the active members in your party.
There is no significant difference if you don't have a lot of companions because active companions are more or less the same with ALL companions.
But it is a significant difference if you have the complete rooster of companions.
In my case I killed a couple of kobolds just for testing and the results were: OFF - 9XP increase for all companions, ON - 18XP increase only for party members. That's like double the experience.
I imagine that the discrepancy is even bigger with bigger monsters.
