But don't move worlds. Just in the world you currently have, remove all the selected mod's blocks. Otherwise you're just compounding issues. Or have you already done this on your current save at some point in time?

In the past I have tried to use MCedit to see if there are any blocks/mobs/items from those mods in my world and there were none. I'll check again but I'm wondering if this doesn't have to do with the items being in the world because it refuses to load even if only an item (non block) is removed from a mod (For Example: The rapier in the Thaumcraft Forbidden magic mod was removed in an update [it doesn't spawn naturally and I haven't made it]). But then again, I might be wrong. I'm going to get MCedit to delete the removed modded blocks and items from the world one by one and see if it will load the world afterwards. This might take a while so I'll get back to you all on that.

well, in the error log, there was several reports of missing textures for Tinker's. It wouldn't hurt to try?

Alright, so I have deleted all of the blocks from the removed mods and nothing has changed. Also I redownloaded and reinstalled Tinker's Construct and there is still no change. I'm just curious but is there any way to figure out exactly what Minecraft is doing when it is loading the world or are the logs the most detailed information I am going to get?

EDIT: WAIT… Something just happened. I just looked back at my minecraft window of when I tried to load the world after I updated Tinker's Construct and now it says building terrain. I think it might be fixed now. I’ll get back to you all in a sec and let you know if it finishes loading.

Your error spam does indicate something very wrong with your world or maybe your install. You should not be missing that many textures, nor getting spammed like that.
You also have version mismatch of bspkrs core which I forgot to mention earlier

[12:09:45] [main/INFO] [STDERR/]: [codechicken.core.launch.DepLoader$DepLoadInst:checkExisting:436]: Warning: version of bspkrsCore, 6.14 is newer than request 6.13

so either update the main mod or downgrade the core mod.

As for the rest, while in game you can gain some information about the mods, sure. Here's a nice guide:

and scroll down to profiling minecraft. Obviously you wouldn't do it for server, but for single player, but same thing applies.
If you really want to get into it hardcore. But I don't know that anyone but mod developers and server admins does this.

It loaded. It got fixed by updating tinker's construct. I don't know what tinker's construct had to do with it but it looks like it did. Thank you all so much for your help. As for the spam in the log, I don't understand why it says I'm missing textures. I don't see any missing textures with anything. I even check nei and the only thing missing textures are items that are uncraftable. Do you think it is safe to leave it here or should we try to get rid of the spam in the log?

If it's not lagging you out, you could leave it but it is rather odd cause it's not just that mods have stuff that they haven't implemented yet. This is definitely of the "should not be happening" kind. Try going through all of your mods and updating to recommended versions. If it worked for tinker's it could be you have similar issues in other mods, something wrong with the files maybe.

I think that since it isn't causing any noticeable problems I'm just going to leave it for the time being. Again, thank you all for your help.

No problem, Glad i could help
