Importer logs warnings when reimporting a LDtk asset that's part of a prefab

Summary

If your LDtk asset is part of a prefab, the importer will log warnings that names are not unique and that subsequent imports may not properly re-link.

Steps to reproduce

1. Add a LDtk asset under an empty parent object, make that parent object a prefab.

2. Reimport the LDtk asset.

Warnings are logged to the console.

I think I found my solution. The error was happening even before the import process was happening. So I think the problems were coming because prefabs were being imported before the LDtk projects were. By changing the LDtk project’s importer’s importQueuePriority, it now imports before prefabs do, and that fixed it, no more log warnings 😄

So what I believe was happening is that because the LDtk project was placed in a prefab, the LDtk project now becomes a dependency of the prefab, so that means that reimporting the LDtk project also means that the prefab gets reimported. And so because the prefab was being reimported first, It didn’t know how to exactly deal with the old LDtk project (because the LDtk project still needed to be reimported next).

So consider this fixed. This will come in the next update. Will close this issue when the update comes 🙂
