Tilemap light bug, how do i fix it, the tilemap turns completly white

how do i fix this

Add to your game 3d box and place it on sceen

i kinda fixed it without 3d box, but i don;t know how, my game is 2d but maybe i’ll try that if it happens again

thanks for telling me, might use it if it happens again

had to use it because bug appeared again, fixed it instantly, thank you
