Alert text variables reversed on Drop Ship en Route

[arquebus_x]

The text should be as follows:

"One of our <UNIT> is heading to <PLANET> to land on its surface."

Instead, it's reading:

"One of our <PLANET> is heading to <UNIT> to land on its surface."

Example: I have a planet named Sichi and a SCS 8th Planetary Engineer going to it. The text reads:

"One of our Sichi is heading to SCS 8th Planetary Engineer to land on its surface."

Ticket 31769, we should be able to fix this for the next update.
