If a Nurgle Daemon unit is within 3" of a DE warlord with the Ancient Evil trait, and within 6" of Sloppity Bilepiper how do you resolve these two rules in the morale phase?

Disease of Mirth: Whenever a Nurgle Daemon unit takes a Morale test within 6" of any friendly Sloppity Bilepipers, roll 2 dice instead of 1 and discard the highest result.
Ancient Evil: The opposing player must roll an extra dice when taking Morale tests for units within 3" of this Warlord and use the highest result.

Roll 3.
Discard highest.
Pick next highest.

In short, it depends on whos turn it is because GW can't write rules properly.
