After any attempt to edit (or even just open and re-save) the tile maps that come with the X2 game examples using Tiled Map Editor, the games now crash with the following message:

The above came from an adapted version of Monster Trucks, but it happens with other game examples too (e.g. Mario).
I am using the latest version of Tiled Map Editor (v1.9.2).
