So does this mean that ONLY numbers > 63 are randomized? What happens if they are < 63 and there are multiple client devices in the network and users have not specifically set bss_color?
Edit: PS, yes I am crazy enough to try snapshots 
But I decided to remain at a snapshot from mid April for now, as with the last snapshots I tried, I experienced laggs with my dap-x1860 (mt7621 + mt7915), which is configured as repeater using the relayd package.
r22573-72780e3eac (stable)
r22900-abec62a542 (laggy)
r23300-86bc525d00 (laggy)
There were so many issues popping up with my chipset recently that i was a little reluctant to try newer snapshots and wanted to wait a little until it all had calmed down a little. I don't know how to code so yeah...
Edit: Turns out, my laggs were caused by bad intel ax200 drivers from the Windows 10 client device. Since I upgraded to WiFi-22.240.0-Driver64, my ax upload instability has mostly vanished and it's all fine now. The Latest snapshot for the dap-x1860 I tried from 2023-07-28 (r23633-daaa0c1b25) was working fine for me. I do not use wds, but unfortunately have to use relayd.
