Jenkins "forgets" GCE Configuration

Every now and then our Jenkins forgets the configuration of the GCE Plugin. Especially the part marked below:

```

gce-google cloud
1
XXX
XXX
123456789-1234-1234-1234-123456789012
# THIS PART IS MISSING RIGHT NOW


```

Does anyone have a recommendation what to do or whether this is a problem with the plugin or with jenkins in general?

Jenkins ver. 2.190.3
google-compute-engine@4.2.0

Start with the reported Jenkins 2.190.3 configuration XML and the google-compute-engine plugin version 4.2.0, focusing on the missing section. Reproduce the intermittent loss if possible and compare the configuration before and after it occurs. Done means determining whether the plugin or Jenkins is responsible and documenting the evidence.
