[RQ]

We have some rubber playmats on our laminate floor (non-glued, click together type) for our daughter to play on. Recently a spill went unnoticed and seeped through the mats onto our floor. This has resulted in a few of the joints swelling in a relatively small area (1 to 2 sq. ft). Since we've left it uncovered, the swelling has dissipated slightly but is still noticeable. Is there any way to fix these areas without plank replacement? (like applying a heavy flat weight to the area) or is replacement the only option. The are is in the middle of the room so I am assuming replacement means a lot of work.

Any advice would be greatly appreciated.
