Last night I noticed that when I swapped out my +6 CHA item off, my DM count goes down by 3 (which makes sense). However, when I swap the CHA item back in, I get another 3 DMs taken out. So swapping my CHA item in and out is costing me 6 DMs. Me thinks that last part is a bug. There's no reason why it should subtract 3 from the count when swapping the CHA item back in. Anyone else noticed?
