[2.1.12] Missing some entites when creating blueprint

[grossws]

Steps to reproduce (in the provided save sa-sandbox-bp-missing-entities.zip with only Editor Extensions mod + SA mods left enabled):

1. Enter remote view and switch to the platform "test1",
2. Make full platform blueprint with Alt+B (or use copy-paste onto newly created platform),
3. Check blueprint for a missing entities, see highlights on the screenshot.

Save is basically freeplay where I:

• went into editor using Editor Extensions mod's Ctrl+Alt+E hotkey,
• switched to Nauvis surface,
• removed all entities,
• filled with lab tiles,
• and checked both "ignore surface conditions" and "generate new chunks with lab tiles".

Then I added bunch of rocket silos with speed beacons & infinity chests to provide materials to the platform.

Also last log file and original save sa-sandbox.zip (with all the mods that were enabled while creating the platform "test1") are attached.

I didn't find a way to make minimal reproducer since copied and manually repaired platform "test3" blueprints just fine.
