Reported: The balance simulation fails with "the database changed under the project": monster rows 1011 and 1012 show m_fExt as "3.747822e+06" where the project recorded "3747822".
Found: Those are the same number written two ways. Before applying a project's change, Studio checks that every cell still holds the value it held when the change was made, and it compared the cells as text. A decimal column the database reads back in exponent form looked like someone else had changed it, so the simulation, and Install, refused.
Fix: Studio now compares numbers by value, so "3.747822e+06" and "3747822" count as the same, and a cell that really changed is still caught. This is in the next GoMMO Studio release.
