Hey, I also got an Hubba NX (1p) and spend 3 really stormy nights in the highlands in the last couple of years. Two went well, the third was... fun.
Wind was at 70kph and rain was intense. I pitched with the straight wall towards the wind, which was my mistake. The ground generelly was a hard pitch. It was September 2019, on the ridge east of Ladhar Bheinn in Knoydart; much more exposed than I'd expected at the time. I am sure it would have held, if I had pitched the other way around. As it was, I was squashed under the tent, most of the time. Unfortunately, the DWR was worn out, so the wind actually squeezed water through the outer fabric. I spent the night wet, but still warm, being out of the wind and with good gear and actually had decent sleep, after I made my peace with sleeping in a puddle.
I'd definitely pin the experience on 1) badly chosen spot 2) wrong pitch and 3) worn out water-proofing. Be sure to carry enough pegs to use all the lines.
My next rainstorm had been down in a valley and less exposed, but the tent kept dry. As has been said: the tentpoles may shift and bend, but this is part the design. 2018 the Hubba saw a hurricane in Portugal and with a much more protected spot, there were absolutely no problems. Had the tent since 2016 in Germany, France, Portugal, Spain, Scotland, New South Wales and I'd only replace it if I could afford a Hilleberg
