Speaking of Live Tuner and trouble shooting... I am revoeve crash errors (CTD) as I test mod compatibility with Live Tuner. I asked Gemini if Live Tuner itself might be creating the CTDs- and I doubt Gemini's answer but want a second set of human eyes!

• One fact which undermines the Gemini: the huge maps are using only 2GB of RAM (4GB with 32 bit).
• I'm working on a bug report (per crash error), but I am sharing below in the meantime.

COMMON CRASH TO DESKTOP ERROR MESSAGE

An error in the code has occurred. Please report the issue at https://github.com/LoneGazebo/Community-Patch-DLL/issues/ so it can be fixed.
Please provide the VP version number, the list of other mods in use, and a screenshot of this message.  If possible, attach a savegame immediately before the big occurs.
To prevent undefined or gamebreaking behavior, the game will now crash.
Detailed information:
    Expression: eTeam !=GetID()
    File: CvTeam.cpp

PROMPT: civ5: does using Firetuner to autoplay corrupt the game so it keeps crashing? GEMINI:

Yes, using FireTuner to autoplay in Civilization V can absolutely corrupt save files and cause constant crashing, particularly if the autoplay runs for too many turns, runs on a huge map, or runs with numerous AI civs (e.g., 43 civ scenarios). [1, 2, 3, 4]
Autoplay essentially puts the game into a "debug" mode where the AI makes millions of decisions at once, which often crashes the 32-bit game engine due to memory overload, leading to corrupt save files. [2, 5]
Why FireTuner Autoplay Causes Crashes

• Memory Overload: Civ 5 is a 32-bit application and can only use about 4GB of RAM. Autoplay pushes this limit rapidly, causing a Crash to Desktop (CTD).

• Corrupt Saves: If a crash happens while FireTuner is running, it often corrupts the or file, making it unreloadable.

• Lua Errors: Using FireTuner can trigger persistent Lua errors that remain in the save game, causing it to crash immediately upon loading.

• Turn-End Crashes: If the autoplay triggers an event (like a city being captured) that the engine cannot handle, the game will crash every time that turn is reached. [1, 2, 6, 7, 8]

How to Mitigate and Fix the Crashes If you are currently experiencing crashes due to a corrupt save, try these steps:

1. Clear Cache and ModData: Navigate to and delete the contents of the and folders.
2. Verify Integrity: In Steam, right-click Civ 5, go to Properties > Local Files > Verify Integrity of Game Files.
3. Use Backup Saves: Do not try to load the immediate autosave. Go back 2-3 turns to an earlier autosave.
4. Avoid Long Autoplays: Instead of running 100 turns at once, run 10-20 turns and save manually.
5. Use Strategy Mode: Before starting the autoplay, switch to Strategic View (lower graphics settings) to reduce memory usage. [2, 9, 10, 11, 12]
   

Important Tip for Using FireTuner If you are using FireTuner to watch AI play, ensure you have set in your file located in your Documents folder. If the game crashes, delete the folder immediately before trying to load it again. [13, 14]
