The command "entreset" does the same thing as well. But it disables the achievements.
The issue: you use a portal but leave the prawn behind. When you come back, the prawn is inside the geometry of the base.
You probably don't have the full F1 menu like in the video but you should be able to do the same trick.
The idea is to force the game to reload the terrain while you are in the prawn suit and the game is already loaded.
I use the PDA to have the mouse cursor.
Bring the "other" tab from the F1 menu, make sure you have "large world debug" checked, then click on "reload" ( prefered ), or low, medium or high depending on your current preset.
Press F1 again to disable the menu and press the jump button continuously until the game reload the close terrain. Do it multiple times if it didn't work the first time.
