I am using this mod on 1.14.4 and everything works except one thing: I can not dig spawner using Axe with Silk Touch. I've noticed the comment in SpawnerEventHandler but I was wondering: are there any plans to fix it somehow? As without ability to move spawners, this mod is very crippled :(

I couldn't recreate your issue on my local machine with the latest mod version for 1.14.4. It works with both pickaxe and axe. Are you using other mods which may interfere with that specific behaviour?

I am using around 10 mods so it might be the case... Can I debug it somehow? I am Java Developer so I can dig into the code/logs if needed, it will be probably faster than starting a new game in Survival and trying to find spawner and getting Silk Touch enchant 🤔

Another question: why this comment it does not work in 1.14 is in SpawnerEventHandler at all? :)

I'm not so sure how to debug with 10 different mods but the thing with my comments regarding it doesn't work in 1.14 is because many of the event stuff was changed in 1.14 and I had to move it. I only commented it out in case it would get fixed soon.
