1.14.4 hopper issues

I don’t know if anyone can help but I am currently playing on a 1.14.4 Papermc server, it runs really great but we have huge issues with hoppers, they either don’t pick up items fast enough, randomly lock up and sometimes completely forget they’re hoppers all together (not picking up items) it seems to be intermittent too with hoppers randomly working, displaying the symptoms above and then working again… It is bizarre but I’d love any advice you can give.

I have a ton of hoppers in several builds and I haven’t had the issue. Did you alter any of the hopper settings in paper.yml or just leave it at default settings?
