so I've installed a ton of flooring over the years. never had a problem with buckling until this past week. the snap together bamboo in the sunroom has been there for over a year now. It had the proper gap all the way around, and now for some reason it's touching both the east and west walls and buckled just a bit. It's an easy enough fix (especially since the buckle is right next to the wall I laid last), but I'm still pretty mad (and confused) about it. but that's a project for another day...
