We have a T5 Construct strata right now in the Jade Titan which has 3 of its 4 floors as Jigsaw Valley, and the last one a random. There's a T2 and T3 Construct gate in Iron Skull with 1/3 and 2/4 of their floors Jigsaw Valley too, and both ALSO have a random.
Now, Jigsaw valley bills itself as "home to a host of mindless slimes and constructs," but in reality it's filled with slimes and beasts, the occasional Timbers, and even GREMLINS. Maybe there will be a room with four or five Puppies.
In what way, shape or form are these "Construct" floors? 1/4 in a Construct strata, fine. But three? And then a random?
And this only seems to happen to Construct: in those poison, shock and freeze strata we all see so much, every floor on every level is of that element, and the types of enemies differ. In Beast and Gremlin, every floor is mainly of that creature type, with each level being varying elements and occasionally having other types of enemies show up, with the OCCASIONAL random or mixup themed floor.
And keep in mind that these are floors that cannot be skipped: they always come in pairs of the exact same floor type, so you can't just wait at the gate for a different one.
PS: Please fix the Deconstruction Zone floor icon: it always shows up with the grey gear that indicates Constructs, rather than the Dark Orange that means primarily Gremlin floors. This can be seen in the Gremlin theme strata especially, where it looks like it's half Gremlin and half Construct, but only because all the Deconstruction Zones are grey (when they are filled with gremlins regardless).
