Is this photo taken after you wiped it up or was it discovered as i see it here?. Mine looks more noticable i think..i'll get a pic later tonight or tomorrow. I have not found any moisture or liquid substance,wet glue etc..on my figure, just that thin black line of dried glue from the tape.
Off to the left and lines up exactly with the edge of the tape to hold the magnet when the belt is on center. The tape on my belt looks like it shifted and there is residue just a hair above the top edge of where the tape has shifted...i'm really not worried at all about it.
Here's what it looked like when first discovered:
After wiping off every trace of the glue I can see that the rubber is less glossy where the glue had been. That's what you see here:
Not a big deal as it's hidden under the belt, but I feel better knowing the tape is gone. I mean why let the glue damage the rubber if you can just peel the tape off and clean it up with goo-gone? It's not like it's hard. Then you can just be without the magnet, or glue it back in place like I did:
