Amarok-6 BKNT Flame Burst : great guitar with a little issue

first of all, great sound, great look, great playability. Components are top notch, and I really like the versatility of the pickups, though they are very hot. Tone and volume pot are okay. Nut is great, so is the neck finish and frets. Setup was between fine and great (nut setting was perfect, much better than my les paul or my american strato). Action was a little high for this sort of guitar, that's supposed to be shreddable. And there was the little issue. I needed a little more relieve of the neck to bring the action as low as it can get, and I got there, so that's okay. The issue is that now the truss rod is completely released with no tension at all; still the guitar would like to have like 1/2 mm more relieve on the neck. Luckily it's great anyway, but it's weird not to be able to relieve the neck more. all in all, anyway, I love it.
