My C++ code seems to revert to an older version whenever I close and reopen the editor. I have to hot reload the code once in order to get the editor to recognize the current code. (Using 4.7.3)

The editor doesn’t load a module built for hot-reload if you close and re-open it. If you’ve been hot-reloading your code, you’ll need to build again after closing the editor to update the module the editor loads, and also to clear out any stale hot-reload modules.
