Im working on a big project and im trying to make it that if the player gets overlapped by a specific enemy in a chase sequence, it would spawn the player in another tilemap, but when im spawned into the tilemap, if i overlap with any tile or just explore it, it says something “program error: failed to cast on null” and the game crashes, please someone help me
