Weird error when using a custom save script.

[Steel Beast 6Beets]

I believe end of file errors happen if one script is performing Marshal.load/save with files that have more or less data than the specific file? Does the same thing happen if you delete the saves and try save/loading?

If it does, perhaps compare the load/save data definitions being used across scripts. The AMS might be aliasing read_save_data, but the KGC script is probably overwriting one (or both) of save/load. In doing so, $ams isn't loaded, which confuses something somewhere.

I could of course be entirely wrong, but I remember having similar experiences with RMXP.

I deleted the old saves and I tried again. It works... without the MACL. With the Method And Class Library, the original error in the OP persists.

Thankfully, none of the many scripts I use depend on the MACL. Getting ride of it shouldn't present any issues.
