[2.0.15] Crash on loading save

[FortressSideDK]

What did I do last:
I had setup a small copper production on Gleba and built an Agricultural tower for collecting jellynut.
I saved the game during version [2.0.14] and came back to continue in [2.0.15], specifically build 80108.

What hapened:
The game crashed during loading the save, during the "Checking consistency Space Age" phase.

What did I expect to happen instead
The save should have loaded so I could continue playing.

Does it happen always, once, or sometimes.
I have attempted to restart the game multiple times, and with multiple autosaves.

Reproduction steps
1. Launch game through Steam
2. Click on Continue Game on main menu or load save from Single Player -> Load Game
3. Wait for game to load
4. Crash during "Checking consistency Space Age" phase of loading

Note and additional troubleshooting
I've run the Steam file validation without it finding any issues.
As far as I could see from the log file, the below seemed to be the issue:
45.892 Error IDWithQuality.cpp:274: consistency check failed: iron-ore, <null>

Active mods
- Base Mod [2.0.15]
- Elevated Rails [2.0.15]
- Quality [2.0.15]
- Space Age [2.0.15]

I managed to fix this by downgrading to 2.0.14.
Then used a remote control tank to do the following:
1. Remove all big mining drills making quality iron ore (still broken in 2.0.15)
2. Blew up/destroyed all chests at the quality iron ore pickup train station
3. Blew up/destroyed all chests at the quality iron ore unloading train station
4. Blew up/destroyed the cargo wagons on the quality iron ore train (wagons had a filter for any quality iron ore)
4. Blew up the quality iron ore electric furnace stack i had
After the above, the game could be loaded in 2.0.15 and I found out I still had a few pieces of quality iron ore in a chest, but not in any furnace or other inventory
