My '08 Terra wall paper wrinkled on the walls, but oddly enough just near the edges and near where the factory added the clear silicone seal. So a lot in the bath room and kitchen.
No peeling, just wrinkled as if it were shrinking
Wife used to hang paper so we got some attractive wallpaper suitable for moist areas and completely stripped the old paper and repapered the bathroom. (looks much better than new)
Same wrinkling in the kitchen area. I got some vinyl peel and stick tile resembling thin subway tiles and made a backsplash extending along the countertop and up the wall to the bottom of the cabinets.
I had no moisture compromise or leaks in these locations, guessing just being in the area of some moisture....
and near the silicone....go figure
