Monster evolution is not happening the first time a monster is spawned

### Describe the bug

Monster dont spawn as the evolved forms when they first spawn in like they should when you are over a year into the game

### Attach save file

[Testing evolution_copy-trimmed.tar.gz](https://github.com/user-attachments/files/20023509/Testing.evolution_copy-trimmed.tar.gz)

### Steps to reproduce

1. Go to a location you havent been to before and see a bunch of non evolved monsters
2. Leave the area by walking a good distance away
3. Return and see a bunch of evolved monsters

### Expected behavior

that the monster properly evolve the first time they are spawned in

### Additional context

in the attached save file go up to the prison to see the non evolved zombies, then walk 10 map tiles away from the prison, after that you can walk back and see the evolved zombies
_No response_

Load the attached save file and visit the prison to reproduce the unevolved monsters on first entry. Then leave by about 10 map tiles and return to compare the later spawn behavior; done means monsters use their evolved forms on the initial spawn as well as after revisiting the area.
