first off, you need to use pastebin for the log file. second, you may need to update something.  i'd check the chunk loading program.

really you dont even answer the question!

[plowmanplow]

You haven't provided enough information for us to assist you. What modpack are you working with? (provide API/Platform URL) The logs are truncated. You should be posting full logs in a pastebin service. Do you have a crash report? Post at in a pastebin as well.

2 people told you to post your logs through a pastebin site.

 

Now I'm telling you, don't spill another log here again.
