Just out of the need to warn you guys... DON'T USE THE MOD "SECRET ROOMS" IT'S SO BUGGY, MY BASE VANISHED BECAUSE OF SOME SECRET ROOMS BLOCKS PLACED, I WAS LUCKY BECAUSE I HAD A BACKUP FILE... BUT THEN IT RUINED MY ENDERMAN XP FARM WITHOUT REALISING IT SO I COULDN'T REVERSE IT...
The problem with that mod is, when there are blocks placed somewhere in the world, it's super buggy: if you teleport from another dimension to or near that chunk with such blocks, that chunk resets. I returned to my bed from The End, and my base was destroyed. Not only that, but while riding your chocobo, this might happen as well, regardless of distance to the secret rooms blocks. I thought I would never teleport to or near my Enderman farm from another dimension, so I used some secret rooms items in the construction of my farm. One day, I was just flying around where lived with my new chocobo, I didn't realise I reset one of the chunks that made up my Enderman farm. So, after I finished playing that day, I made a backup of that world (the world which had the corrupted enderman farm) The next time I played, I went to my Enderman farm and found that its most essential part was destroyed... I was furious and rage quit never to play in that world again...
PLEASE ACKNOWLEDGE THIS DEADLY CURSE AND BURN ALL YOUR SECRET ROOMS ITEMS IF THERE IS ANY.
