I was playing another mod and I crashed, and now I can no longer open that save file without the game crashing every time. I posted the crash report on the mod's GitHub page, but since Mariculture is mentioned in the crash report I thought I'd post it here in hopes you could help me out as well.

Here is the report: http://pastebin.com/tNnRh4qe

It happened when I entered a portal to a different dimension in the other mod, now I'm either stuck in the portal or in the other dimension with endless/permanent crashes upon loading.

Add the dimension to mariculture's worldgen blacklist in the configs

Ah, awesome, I'm glad there is a fix! But where is this blacklist at? I have the world-generation.cfg file open (assuming that's what you mean) but I don't see any blacklist to add the dimension to. The only thing I see is something under the Aquatic Generation section

I:"Ocean Generation > Blacklisted Dimension IDs" <
-1
1
>

So, how do I add it to the blacklist? The Id is:
I:"Ancient Treasure Room ID:"=-34
but I have no idea where to add it to the config. I tried simply typing -34 in the brackets but it didn't work.

Should it look like this?

I:"Ocean Generation > Blacklisted Dimension IDs" <
-34
-1
1

If so, it's not working. I've edited the file as such and created a new world and it still crashed. Am I doing this wrong?

That should work. If it's not, then you must have the dimension id wrong. If you have another way to obtain limestone/titanium you can also disable it entirely by disabling the biome replace top blocks config. (or whatever it's called).

The replace top blocks option worked. I'm going to turn it back on after I exit the dimension and hope it doesn't cause too many problems. Thanks for helping. :)
