I got this error report when clicking on a new migrant

Summary:
The “Saving…” does not disappear after saving manually. Here’s the error log that appeared before I saved manually, while viewing the crafting queue:

Some screenshots of the issue:

Note that I am using a Terrain colour mod.

Steps to reproduce:

  1. Open Wood crafting queue with more than 1 worker active
  2. Wait for a worker to complete an item
  3. Save the game manually

Expected Results:
The game remains playable and UI elements can still be clicked.

Actual Results:
The main menu can still be opened, but clicking elements yields no results.
The bottom toolbar cannot be clicked. Also, no elements in the world can be clicked - they still light up, though.

Restarting the game works fine. The loading screen appears and no data is lost.

Notes:
As previously stated, I am using a Terrain colour mod. Other than that, I also imported quite a few builds and removed the item limit and upped the population limit.

Also, it seems like this person got the exact same exception string.

Attachments:
Savegame after the game loaded back up (waited a few minutes)
