Phalanx can track fleets originating from a planet, and with some extensions from asteroids and coords.
How about fleets originating from a planet and then recalled?
You can't track those in oGame and it was an accepted (but long) FS strategy.

only fleets send from planet with mission deploy which have been recalled cannot be phalanxed

I must have used transport. tyvm.

One more question about deployment:

You can't get lanxed if you deploy and recall. Do you get lanxed if you deploy and return because of missing destination?

yes....return deploy because of missing destination like non-existent moon/insectoid entity cannot be phalanxed

Tyvm:)
