This creates a problem where when you create a surface with box size larger than 99.99 the box size is read as 99.99 instead of the original size. One quick work around could be converting the box size to nm instead of Angstrom.
As of 91ae5f4d72891ed9e1fb15e44d479653eb52388d the box size in LAMMPS setup is now displayed in nanometers.
This limits the box size to 100 nm instead of 100 Angstrom.
It's a temporary solution.
