Critical Map Corruption - Saved file has severe model glitches, incorrect sizing, and misplaced parts

[ledutuu]

Hi @Devraj2010isme,

I am writing to report a critical issue regarding the accuracy of the saved map files in the recent versions of BetterSaveInstance.

The tool no longer exports the map correctly. The saved .rbxl file suffers from severe visual glitches and data corruption. Specifically:

• Model Corruptions: Almost all meshes and models are completely glitched out.
• Incorrect Transform Data: The size, shape, and positions of the parts/instances in the saved file do not match the original game at all.
• Glitchy & Corrupted Environment: Objects are floating around randomly, scaling incorrectly, or missing entirely, making the downloaded map completely different from the actual game.

It looks like the buffer handling or the property serialization (perhaps related to optimization tweaks like AlternativeWritefile or TreatUnionsAsParts) is breaking the physical structure of the map during the saving process.

Could you please review the map compiler logic? Thank you for your time and hard work on this project!
