Ouch, that was way harder than 3 diff for me! Cool opening works at first, then I had to concentrate a lot in the middle to finally figure out the desired logic :o

Difficulty is indeed probably closer to 4. Estimated difficulty was based on the testers feedback.
And yes, the midsolve logic sequence is trickier to spot, but it is still based on the same kind of properties as I used in the opening. Glad you figured it out eventually!
