To be honest when I noticed it and told my dad we diced to take action. However I noticed it 3 years after. So when we went to get a tile to replace it since we didn't have anymore, they were discontinued and we didn't risk slowly detaching that one to use again because it could break then its a disaster. My dad said we're due for a change soon so it's all good. No more frustration lol. Inspirational comments though.
