In nilfheim mission, its most of the time impossible to expand on the portal tile

In the Nilfheim mission of the bifrost game mode, when you try to expand on the tile past the portal, with the new main house, the loading progress to conquer the tile will max out, then the sound effect will play endlessly and non stop, while the progress bar is stuck on 99%, and the tile will never actually be captured.

I played a 3 man game and a solo game, and this happened 4 times out 5.

This makes the missions unplayable/not interesting, as you cant conquer the tiles on the new islands.

STEPS TO REPRODUCE:
- clear the tile past the portal, with the new main house
- press "colonize for 0" button
- The tile will never be colonized, the sound effect plays on a loop
