Mobs stoped spawning during raid

About half way into the raid maybe, no pillager, ravanger or other mobs just didnt spawn. i had just defeated a ravanger and it was regenerating or smt, and once the load was done, nothing spawned. I was looking all around the village and nothing was there, even the iron golems and the villagers. 

NOTE: its in pocket edition and not in java. i dont think there was an option for pocket edition
