Wall geometry doesn't update instantly

Steps to Reproduce:

1. Place any wall block;
2. Place another wall next to it.

Observed Results:
The newly placed wall will already have the updated geometry from the beginning, while the other wall will take longer to update.

Expected Results:
The wall's geometry gets updated instantly, at the same time as the newly placed one.
