I think I've found a bug, thought it was me going crazy but I've seen it a few times now.
Using firmware 2.7 I have the first performance setup with four profiles. Occasionally the profile from the fourth slot is duplicated,stomps and all, to the first slot, but the name remains the same. The profile name changes, but the profile has changed and the the slot name remains the same. Every time it's been that way from power up, but I defiently have saved the performance before the last power down because it's my gigging one and I use it a lot without tweaking and saving etc for many reversals and gigs with no problem. Ive only noticed it on this one performance though and when I use a different performance for home use it never seems to happen.
Anyone else seen this?
