This command can be used to check that saving is functioning correctly. It will make a save file named 'Test_01', load it, and then save that again as 'Test_02'. The two files should be the same (in size, etc), if not, there is likely a problem with saving.
savecheck
savecheck
Running the above command would initiate a save check. As described in this command's description, the save check will create two files - Test_01 and Test_02 - they should be the same if your save functionality is working as it should be.
