Now, if not all tiles on the spawn circle can be owned, the algorithm tries to select another random spawn tile.

Please complete the following:

• I have added screenshots for all UI updates
• I process any text displayed to the user through translateText() and I've added it to the en.json file
• I have added relevant tests to the test directory
• I confirm I have thoroughly tested these changes and take full responsibility for any bugs introduced

Please put your Discord username so you can be contacted if a bug or regression is found:

Walkthrough

The changes add validation to spawn tile selection by introducing overloaded function signatures in getSpawnTiles() that support strict validation. When enabled, the function rejects spawn selections if any tile falls outside land boundaries instead of filtering invalid tiles. The spawn execution logic uses this strict mode to ensure selected spawn locations are fully within land.

Changes

Cohort / File(s)	Summary
Spawn tile validation function src/core/execution/Util.ts	Added overloaded getSpawnTiles() signatures with new optional requireAllValid parameter. When true, returns null if any spawn tile is invalid; when false (default), filters and returns only valid tiles. Supports type-safe calling conventions for both modes.
Spawn selection safety check src/core/execution/SpawnExecution.ts	Added guard condition in randomSpawnLand() that calls getSpawnTiles() with requireAllValid: true to validate the chosen spawn tile is fully within land boundaries. Continues tile selection loop if validation fails.

Poem

🌍 Spawn tiles dance with new grace,
Checking bounds with overload's embrace,
No more tiles lost to borderland's face,
Validation guards each sacred place,
Land-locked spawns now stay in place ✨

Title check	✅ Passed	The title clearly describes the main change: improving random spawn selection to avoid spawning near water, which matches the changeset's addition of validation to ensure spawn tiles are fully within land.
Description check	✅ Passed	The description is directly related to the changeset, explaining the fix for spawn tile validation and the new behavior when tiles cannot be owned due to water proximity.

_{✏️ Tip: You can configure your own custom pre-merge checks in the settings.}
