I have changed manually all of my 14 NUC full node for the v2 database after updating client to the version 1.3.5 because some of my chia windows app have continued to work with a part of the v1 database and my NUC have only 256 Go of SSD.
Since I have not wining. Normally, I win every 2-4 days.
You did run the .\chia db upgrade correct? It would have changed the config.yaml to V2 for the main node section, you just had to change the wallet to V2 enven though they said in KEYBASE that it talks to the V2 database in the code.
After copying the v2 db on all NUC without regenerate the config.yaml file it seems not working correctly but re-generate by the client on all NUC the config.yaml file and this farm re-started to win now every 2-3 days as expected.
The v1 and old version of the windows client break all NUC windows chia app each time a client on the network win. Of course it was necessary to restart all client app each time one win (with older version then 1.3.5)… (this is my older bug of a past month)
