Exterior wall plastering step bugged

[Riku]

Im doing a skybox random generated bp and im at the step where i placed on all exterior walls the insulation boards, but i cant plaster them so im just completely stuck either restarting the bp completely or skipping the step entirely

Hey! If you can't plaster the exterior walls then you most likely haven't laid all the styrofoam. Please check under the windows.

you were right xD somehow i missed 2 parts because they were in the sun even tho i went around even closely like 20 times around the house i missed them xD
