Set Desired Stance doesn't always seem to work when using custom stances?

[xkamronx]

I added some custom stance gameplay tags where required, then added a 'force' for the tag to be set from another post here that said it had to do so to make it function to begin with.

When I call Set Desired Stance (it's currently being set on a RepNotify for driving, for example) it doesn't always seem to update across the network, and thus the character isn't in the driving animation on other clients.

Void AAlsCharacter::ApplyDesiredStance()
{
	if (!LocomotionAction.IsValid())
	{

		Stance = DesiredStance;     // < Added this line to force custom stances

		if (LocomotionMode == AlsLocomotionModeTags::Grounded)

If I'm calling this setup wrong to change the character's stance with Set Desired Stance, what is the preferred method for actually changing the character stance to add other actions / states to ALS Refactored?
