Spawners spawn mobs only at a very low distance

[PulcioPappi]

Hello everybody

I just found a dungeon with three spawners on my LAN world where I play Crucial 2 with my brother, and we tought to make a combined mob farm in order to make all the three spawners drop mobs in a single spot, since they were very close. So we digged out and cleaned the space around them and placed some water to make the mobs that spawned flow to one single hole. After it was all ready, I realized that the spawners weren't spawning anything. So I broke all the torches around them, but they still wouldn't spawn. Then I found out they worked only if I was a few blocks away from them, like 5, then I tried to change some options in the video settings menu because I tought the Magnesium mod was the issue, but it wasn't. I searched a mod in the modpack that could be the issue, but I found nothing. It's not a very important issue, and I don't think it's a bug, but I really want to know if it's normal that I have to be so close to them.

I also have some other mods installed on the modpack, but I really doubt they would interfere.

Bye
