[2.0.15] Space platform foundation is not prioritized in requests for construction

[dzikakulka]

When a space platform has "Auto request missing construction materials" checked and ghost entities placed on ghost foundation tiles, there doesn't seem to be any particular ordering in fulfilling created requests.

With big enough builds (large blueprinted platforms) this can lead to a frustrating deadlock where the hub inventory space is depleted before any foundation gets requested and arrives, which then needs manual intervention to drop some of the (still needed) materials, wasting time and rocket launches.

While I agree that normally logistic network should fulfil requests in an unspecified order, this case could use an exception to make building space platforms at scale much more convenient.
