That was explained. I read somewhere that Ukrainians were making wooden replicas and heating them up from inside with simple grills or gas cookers to fool the thermal imaging of Russian scouting drones and get Russians to attempt kalibr strikes. Russians, knowing the missiles weren't intercepted and hit their targets relied on images from their drones and marked those as destroyed himars launchers. Kalibrs are quite expensive so even if we believe that some of those 44 hits were real units not dummies it still looks pretty bad for the Russians.
