I've seen a couple guys experience this and it just happened to me.
I use spillover all the time. It's always turned on. I have performance that will NOT spillover when switching to rig 2 from either 1 or 3. Other rigs spillover just fine.
Anyone experience this or know the fix? I've tried copying/pasting things around. Even drug it into Rig Manager, deleted from Kemper and drug it back on. Same thing. Just now tried saving it with "Rig Spillover Off" selected on every slot and then going back through and deselecting that and saving again. Still no dice.
Very strange.
Thanks in advance
