[BUG] (Incompatibility with Roads of the Rim) caravan unable to travel from land tile to ocean tile with glitter road

[AlisonHuang777]

Describe the bug
Context: Roads of the Rim is a mod that gives the player the ability to construct roads on the world map. Advanced (custom) roads like glitter road can be constructed on impassable tiles and make them traversable.
Caravan cannot travel from land tile to ocean tile, provided the required road already exists.

To Reproduce
Steps to reproduce the behavior:

1. enable dev mode
2. launch dev quicktest
3. enable god mode
4. finish all research (or only the required ones if you know which)
5. form caravan and travels to any land tile that is also adjacent to any ocean tiles
6. designate construction of glitter road (the only road that is allowed to be placed on ocean tiles) on any adjacent ocean tiles
7. construction is instantly done with god mode enabled, but the caravan can not travel to that ocean tile with road

Expected behavior
Caravan should be able to travel to the ocean tile with glitter road constructed.
