I recently noticed that save files from my Debug builds in Visual Studio 2022 were incompatible with my Release builds and vice-versa. I tracked it down to the Global Optimizations flag (/Og) in the compiler, which is included in the list of optimizations turned on by both /O1 and /O2.
My version of MSVC in VS2022 is _MSC_VER == 1939. I figured this was caused by a fairly recent change in MSVC so I tested in VS2019 _MSC_VER == 1929 as well. The optimization works fine in VS2019 so in lieu of trying to install and test every version of VS2022 to narrow it down further, I just disabled the optimization for this one function for all versions of VS2022.
