You mentioned earlier that you only tried the boxes about 6 years ago.
Could it be they have identified the issue and fixed it, because I've got hundreds that are around 5 years old and not one is showing this sort of damage.
My Swientys are still full of bees and when the the curves get chewed I bodge them with propolis, wax, anything else to hand and duck tape.
Swienty have definitely not fixed it: the pic on C Wynne Jones website shows the boxes still have the curved lip; it's likely that the cost of adapting the mould to square cut the box was not financially viable (I'm guessing). If you put a square-cut box on top of a Swienty the gap at the joint exposes the thinning curve to light, and bees do the rest. The peak of the curve is the point of contact with the box above, and as this weak point is then propolised it fragments when boxes are parted.
