[BE & Realms] Pillagers are NOT spawning at Outpost after building raid farm

I tested a raid farm on a personal creative world and it was working great. However, once I built the design into a Survival Realm, the pillagers stopped spawning entirely. Not on the tower, not around the tower. Difficulty raised to HARD and still nothing. I feel like I've wasted 4 hours building this due to this bug. Mind you, this is the SECOND design I have tried. Worked in Creative test world, failed on Realm...
