Well, that was quite the diatribe above so here is a more reasoned look at the issues of led burnout and code loss/disruption -
- Plastic may not be your friend - Plastic-y frameworks/assemblies certainly can, and Do in my case develop big problems with static build-up. My test-frame that caused so much trouble is a 1 meter PVC tube cube frame with lots of criss-crossing light strings) I can develop significant static charge. I am actually not sure about what to do about this except ground everything (see below). Of course static can destroy LEDs pronto. And if editing code on the PB, delete the code. Likely static buildup is just really “annoying” to running code, causing all kinds of weird effects for a while before actual burnouts start to occur.
I’m thinking of this may have at least some small bearing on @UnstoppableDrew’s observed weirdness outlined in his post -

Not being too familiar with the nanoleaf but having watched their production video I see they are quite plastic-y.

Grounding IS your friend - Diligent and thorough. Well thought out and carefully executed. Do it. (Talking to self also)
-
Working hot, or not - Working with a hot network of LEDs is probably not the best idea unless you are totally Zen and careful about it. The slightest mis-wire and zap!, there you go, stuck pixel, or worse.

Fairy Lights as Antennae? - I’m not sure about this either but the LED strings I’m using BTF Addressable 2812B Fairy Lightssure look like prime candidates for acting like antennae - I mean there you have parallel data power and ground conductors running the whole string length. And I’m running upwards of 350 px per channel.
Here’s a pic of the randomized mess. Not sure what channel, but it sure looks like I could tune something in with it -
This second pic more clearly shows where I Twisted the conductors together somewhat for strength and handling improvement (perhaps antenna suppression) … but I found the twisting behavior to be unpredictable and risked breakage of the string
