That is unfortunate. Choosing dual-data pixels (i.e. 4-wire pixels with backup data) like WS2813 (5V), WS2815 (12V), WS2818 or GS8208 (12V) can be more reliable as in case of pixel failure they're designed to allow the data to pass over it and onto the still working pixels down string. Nearly my entire display is made up of the 4-wire pixel variety. One dead pixel on its own is much less obvious than say half a string going dark from a single failure.
