Mod Pack Version: ATM 7 0.3.20

I've been experiencing this issue since 0.3.18/17. I'm playing the pack on a server with four friends and we are all on the same team using FTB Teams.

I'm able to easily claim and force load any chunks that I wish however, those chunks do not stay loaded. This is evidenced by a hose pulley in the nether failing to pump lava when I'm not nearby, a hose pulley in the overworld failing to pump water whatever I'm nearby and several machines in the compact machines dimension not processing materials when I'm not inside the compact machine.

I'm able to get around this by making the chunk loader from extra minecarts but even that's a little bit buggy. They only seem to function while I'm online and after logging on I have to turn them off and back on again in order for them to start chunk loading.

I've checked the FTB chunks config on the server and it is set to allow chunks to be loaded while a player is offline so I'm at a bit of a loss and it's a little annoying.

seems that already set force loaded chunks from 0.3.18 are still working for me however after updating the mod packs no new ones work

Hmm, maybe that's the case for me. I don't have many chunks from 0.3.18 loaded so It's not easy to test

I have experienced this while trying to force-load chunks within compact machines on a server in version 0.3.21. output from the compact machine would stop after a few seconds and would not resume unless i entered the machine. Though i have not fully tested if it is at least loading the overworld chunks at all i am thinking that would be something to look at as well.

People on a server I look at have said the chunk loading breaks when no one is in the dimension. I've tried enabling the Mekanism chunk loader but that hasn't helped. v0.3.22

This is just like before the upgrade to 0.3.x where none of the mods with chunk loading worked but you can used the vanilla "forceload" command to load chunks and they stay loaded. I commented about this a couple of months ago on the FTB issue that was open about this. I don't know if the mods go through forge to execute the "forceload" command or if they do something else but at that time it looked like mods were processing the chunk loading request, but it was never actually being executed.

UPDATE: I noticed that the FTB team had released a new build of chunks today, ftb-chunks-forge-1802.3.6-build.145, I put it on my server and tested chunk loading and it seems to work fine. I tested it first with a vanilla furnace smelting glass. And then I tested by claiming chunks with IE waterwheels producing power for an Iron Furnace smelting cobblestone and it worked for it too.

I don't know if this resolved any conflicts with other mods that have chunk loaders or not.

BTW I'm on ATM7 0.3.22

Yes the new FTB Chunks version has fixed this issue.

Thank you for all the investigations into this issue guys and finding out it has already been reported, and now fixed, will close this now
