[2.0.76] Corrupt map. Unknown decorative ID: 1107

[NightMunky]

I went afk last night for a few hours, then came back, saved the game and exited without any issues. Today I noticed the main save and all 3 recent auto saves get the error 'Corrupt map. Unknown decorative ID: 1107' when trying to load the game.

I believe this issue was caused by poor connectivity to the 2nd hard drive in my computer where factorio is installed.

Unfortunately, the most recent backup without this issue is 4 months old and I really really don't want to lose all my progress. Is there any way to fix the save file?

This looks like a memory bit flip, one byte had a value of "04" when it was expected to be "00" and as such one decorative had an incorrect value preventing save from loading. Attached is a fixed save file.
