mapgen resolves terrain ids to int_id before all terrains are loaded #82974
Description
Describe the bug
While working on #82965, when loading into the game I got a message that t_rock_copper was invalid terrain. Which is a lie because it's defined right here:
(Same with the other subsurface terrain in that file)
Attach save file
N/A, happens on new game.
Steps to reproduce
- Use data from the above PR
- Load game
- Error message appears
Expected behavior
The game does not tell me that terrain which very definitely exists does not exist
Screenshots
Tests on the PR show the following error:

Additional context
Renech suggested this may be a problem of loading underground before loading modded terrain, and indeed when I replaced the innawood vein terrain with vanilla terrain like t_rock_red the game loaded with no error messages
