Thank you, this is very helpful.

Only add-on comment on your last sentence ... I deleted the "optimize" folder but then Kibana would not start giving me the following (main) error:

```
FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

```

I managed to deal with it by following this [post](https://github.com/elastic/kibana/issues/18944) and by increasing the heap memory:

`NODE_OPTIONS="--max-old-space-size=4096" /usr/share/kibana/bin/kibana`

This way it managed to get through the optimizations and rebuild the 'optimize' directory.
