What did you do?
- Tried loading saved game without mods (reverting to pure vanilla to bug-check something)

What happened?
- Game crash on loading the saved game

What did you expect to happen instead? It might be obvious to you, but do it anyway!
- Should load the saved game without any of the mod entities or logic

Edit: Removed MacOS tag because of below post

Just had exactly the same happen to myself as well - I'm, running Windows 10 so issue not isolated to MacOS as post title suggests.

Attaching my log files.

Note: Using the "Sync Mods With Save" works and the map loads without error, just occurs if you load without the correct mods active.
Note: Using 0.17.3 I was successfully able to load saves without the correct mods active, and the appropriate entities were removed correctly.

Thanks for the report. This should be fixed in the next version of 0.17.
