I have been putting together a modpack (mainly for myself, and possibly for others in the future), and I haven't had too many issues, and those I have had, I have been able to resolve relatively easy, though I've been playing in the world for a bit now, testing things out, adjusting config files as I go, etc, when I came across this crash that keeps repeating itself. I can load the world, and I have enough time to move a block or two, and then the game crashes.
I would initially assume that there is something loading from a mod that hasn't loaded before and is causing the game to crash, but I've been through this area a few times now, and this time it is failing.
Below is a sample of the Crash Report that I think is where the bug is claimed (at least this is the area I've used to resolve most of my issue before):

I'm not exactly sure what is going on here, is this is the spot I should be looking at (I can attach the rest of the file as well). From reading this, I assume it is saying that there is an issue loading a chunk, possibly a conflict between Minecraft and Forge?
Though I couldn't find a fml-client-latest log file (I searched through the modpack folder, and the original Minecraft folder, and did some searching online on where it's located, and supposedly it's in the log directory, but haven't been able to find it), here is a copy of the latest log file that I found within the log directory within the modpack directory:
(It requires two links, because I don't have pro version of pastebin.com)
After replacing the mod with it's older version, as I mentioned earlier, the game loaded fine, but, now I am getting the same issue when returning to a former chunk.
I could just remove the mod, and I could try to replace it with the newer version, but both of those are undesired.
Any suggestion on how to dive deeper into this issue so that I can better understand and resolve it?
A specific block is causing it. If you have backups, restore them and hope it works. If not, try removing everything from TAN using MCedit in that region
Thank you for looking into this and getting back to me.
I dove deeper into this issue for a bit trying to find work around with it, and you are correct that removing everything via MCedit in the region, or even finding the specific block, will resolve the immediate issue, but the issue keeps returning.
Every world I create, after I reach a certain point in base building, or so it appears, once I leave an area and come back to it, there is a block that causes a crash. I can continue loading into the world and slowly move away from the block that is causing the block, and sometimes the block will go away completely, but other times if I attempt to return to that area the issue comes back up.
I started going through and removing each mod one by one to resolve the issue by locating the specific mod, but I wasn't able to boil it down, which makes me think that maybe there are multiple mods conflicting....ugh...
I really want to understand how to find where this is happening so I can source it to the specific mod and either remove the mod or make some edits to it myself to resolve the issue.

Any thoughts? Any suggestions?
Add the full report and the fml-client-latest.log
Use pastebin.com
Thank you for the direction to pastebin.com
Here is a link to the full crash report:

Test it without toughasnails
Oh no! Not Tough as Nails! That was one of the core ideas that this modpack was based around....
I will give it a shot.
Can you tell me where/how to found that? I would like to understand the code better myself as well.
It is a guess because the last action before crashing was:
[11:23:49] [Client thread/INFO] [toughasnails]: TAN configuration synchronized with the server
You will find it in the fml-client-latest.log
If it is working without it you can try another version:
https://www.curseforge.com/minecraft/mc-mods/tough-as-nails/files/all?filter-game-version=2020709689:6756
Your guess was correct.
Removing that mod allowed the world to load up properly and I could move around and act again.
Do you know what was causing it, or how to begin to resolve it, so that I can continue using that mod?
I don't know why - test it with the last "release" build
Build 3.1.0.139
https://www.curseforge.com/minecraft/mc-mods/tough-as-nails/files/2644652
I'm currently running 3.1.0.141, though it's labeled as Beta, and not release.
I will give that a shot then!
Adding that version of the mod into the modpack allowed the world to be loaded back up.
Thank you for your assistance in helping me (effectively guiding me through) with this issue.
