I occasionally have a similar problem. The Pod X3 LCD screen changes and the star (*) shows up on the left side of the LCD. Which means that some setting has changed. In my case it was the tone volume that was changing. Turned out it was a scratchy tone volume pot. My solution was to back-and-forth the knob a few times, then park the knob at max. It still happens now and then. Happens a lot less when the tone volume knob is parked at max. Happens less after the X3 has warmed up, or has been turned on for several minutes. So, before use, I turn it on and let it warm up. My quick fix is to switch to another tone, then back to my original tone. It's then back to correct. When the tone gets changed by the bug, and the star shows, it's not permanent. The change hasn't been saved. So switching tones, then back puts the tone I want back to it's original (last saved) state.
