Milighthub on Feather Huzzah "forgets" configuration
Describe the bug
After more than a year of service, my milight-hub instance running on a Feather Huzzah seems to have become "forgetful". In the span of a day or less, all settings except the wifi config and the theme will reset to the defaults. The /settings endpoint returns a valid but "default" json document, and the interface has lost my aliases. Restoring a backup gets everything back to working order, until the configuration is forgotten again.
This behavior started happening last week, and is now an approximately daily occurrence.
Steps to reproduce
Sofar I have not been able to reliably reproduce the issue. Restarting via the webinterface or power cycling the board does not trigger the forgetfulness.
After a couple of hours the configuration will be reset
Expected behavior
The configuration is remembered.
Setup information
Milighthub on Feather Huzzah (8266) with a NRF24L01+ radio.
Firmware version
Current Version: 1.10.8 (huzzah) Issue started happening with 1.10.7 (huzzah), upgrading to 1.10.8 did not change it.

Same here with nodemcu. It was a daily routine to upload the config json for a while. I've switched to D1mini and the problem solved. 1.10.7 & 1.10.8 firmware downloaded and locally built gave the same problem on nodemcu. Now the D1mini has downloaded 1.10.8 and remained intact since more than a week.
I have also since replaced the Feather Huzzah with a more compact Wemos mini D1.
My hunch (with nothing to back that up) is that perhaps milight hub - under certain circumstances - writes to the configuration too often which leads to occasional corruption. That would explain why the forgetfulness started happening after more than a year of working just fine and also why switching to a new microcontroller fixes the issue.
