Syncthing resets

LMDE7 x 2, OMV8 x 1 (or Deb x 3) v2.1.0, Linux (64-bit Intel/AMD)

On all three machines reboot seems to reset everything in ~/.local/state/syncthing to a new state with a new ID, no shares, no password on GUI, non multi gig database, everything reset.

At first I thought it must be a permissions problem but another kernel update came through today and it happened again, on two machines and I haven’t rebooted the other.

Any ideas?

Docker, volumes, not properly mounted?

No. Apt installs from the apt.syncthing stable repo.
