According to the youtuber Hypnotizd, the mega torch prevents ExU2 spawners from working. Need to investigate.

Just tested with cursed earth (working) and the Resturbed Mob Spawner (not working).
I'll take a closer look into the mob spawning code, hopefully I can use the workaround used in #2

I realize this issue has been closed for half a year, and the fix does partially work. But I found that I had to break the mega torch and place it down again in order for ExU's resturbed spawner to start working. After that it works fine.

Glad I went searching for an answer, I noticed this issue as well. I was wondering why even though it is supported the Extra Utilities 2 Spawners were still not spawning, cursed earth was working fine. Found this issue and indeed, breaking and replacing the torch does fix the issue. Odd.

We are on 1.10.2 btw, running version 1.4.1.34
