.Sav file size is massive on packaged builds

I have a sports game that makes use of the savegame system to store very large amounts of statistics. It works great in editor. The .sav file sizes are manageable and the system is smooth. However, when playing the game in a packaged/shipping build, the file sizes bloat to over 10x the size that they were compared to in editor.

For example:

In my game, I start a new sports season and simulate one week worth of games. In editor, the save file is 6.43 MB. In packaged build, the save file is 81.6 MB.

Is this to be expected and I’m missing something or is this a bug?

Thank you

Well I don’t know the answer to your question but I can tell you that its probably not normal, my .sav files are nearly the same size after packaging as they are in editor.

I’m so confused. I can’t understand what could possibly be running differently when its the same exact code.
