As it so happens, version 1.1.5. of P.U.M.P. was uploaded less then an hour ago, which might already have a fix.
P.U.M.P. didn't raise an event after the ghosts are placed. This event was needed for another mod, too. (Kudo's to Ferlonas for offering that pull-request).
And if I look at the description of Construction Planner Continued, I suspect it depends on that same event.
Can you update P.U.M.P. to the latest version and let me know if the issue persists?
