Summary of the problem [1.7.0] FTB Utilities + RFTools Dimensions = Chunkloading problem. Pack Version 1.5.3 What is the bug? Currently you need to use FTB Utilities if you want to chunkload chunks in Beyond. But sadly I'm running into a problem with FTB Utilities and RFTools Dimensions regarding chunkloading where chunks won't chunkload in RFTools dimensions upon reloading the world. if I load into my survival world, I first need to teleport to the RFTools dimension where I have chunks loaded. I then need to completely unclaim those chunks, reclaim them and re-chunkload them before those chunks actually start chunkloading. I need to do this everytime I reload my world, and it's quite annoying as there's no other way of chunkloading available in this pack. Mod & Version FTBUtilities-1.1x-3.6.3 & rftoolsdim-1.1x-4.55 Link to log file Is it repeatable? Yes, everytime upon reloading my world. Known Fix travel to the rftools dimensions, unclaim and reclaim the chunks and re-chunkload them.
