Simulation error EndDeserialize(GameAreaManager) tag mismatch

Symptom

• Simulation error: EndDeserialize(GameAreaManager) tag mismatch

Cause

This happens when you save a city with 81 Tiles mod active, but then later load that city without the 81 Tiles mod.

Solution

The 81 Tiles mod must be active when the city is loaded.

Fixed?

If not, check the workshop page for 81 Tiles.
