Guardian farm?

Just recently we started playing online Minecraft and the server team and me and got updated to Minecraft 1.14.3.

But it seems like my guardian farm is now broken. It was working just fine on Minecraft 1.14.1. It spawns guardians in many waves that come once about every 2 minutes or so.

Did they change guardian spawning mechanics again or is the server just being weird for some reason?

It’s bad enough we already tried to rebuild whole fine but as you can imagine that didn’t really help.
