Bug Report

It appears that the registry for fluids that Immersive Petroleum uses for looking up drilled cores and pumping has been shifted or changed in some way. This means that any time you look at a core sample from before 3.1.0 it will crash you and all pumps that exist prior to will either spam console or crash as well.

Possible solutions

Immersive Petroleum needs to update how it renders to not give a Null Point Exception, or pump results need to be the same between versions.

Steps to Reproduce (for bugs)

1. Install 3.0.8 and create some Core Samples.
2. Place the Core Samples in the world.
3. Put Pump Jacks down on areas with oil
4. Update to 3.1.0/3.1.1.
5. Look at the Core Samples. Enjoy your client crash.
6. Observe your console to see the errors, load some chunks with Pump Jacks to see if they crash you (crashes are not always guaranteed).

Thanks for the report, this may sound like an odd question but it is related. Do you know what biome you're doing this in?

I was going to submit a new bug report but I'll post it here instead to not spam the issues.

Bug Report

Journey Map Staging is currently broken in 3.1.0/3.1.1 and as a result it's breaking /crafttweaker/postInit.cz. It seems like it doesn't register properly in CraftTweaker.

So far I've noticed that this caused issue #3644 by making all of the Immersive Petroleum pump jacked fluids to be unregistered.

function initSpecificStaging() {
        // Staging Specific Scripts
        scripts.crafttweaker.staging.containers.init();
        scripts.crafttweaker.staging.dimensions.init();
        scripts.crafttweaker.staging.enchantments.init();
        scripts.crafttweaker.staging.journeymap.init();
        scripts.crafttweaker.staging.liquidAndGas.init();
        scripts.crafttweaker.staging.mobGear.init();
        scripts.crafttweaker.staging.mobs.init();
        scripts.crafttweaker.staging.multiblock.immersiveEngineering.init();
        scripts.crafttweaker.staging.ores.init();
        scripts.crafttweaker.staging.tinkers.init();
        scripts.crafttweaker.staging.waila.init();
}

Everything in the above category is most likely not working right.

Possible Solution

Hot fix JourneyMapStaging to work with CraftTweaker.
Comment it out.

Steps to Reproduce (for bugs)

1. /ct log
2. grep -i "error" ./crafttweaker.log

What do you mean journeymapstages isn't working right?

There are no errors in crafttweaker.log in my unmodified instance.

Hmm I guess something must have gone wrong with my SevTech Server zip. There was no JourneyMapStages was corrupted or something, once I downloaded it again separately from CurseForge it seems to be working fine.

Sorry for the confusion. I lost like 5 hours on this. >.<

After further investigating it seems Excavation over all is broken. Trying to create a new core sample doesn't give you anything when you right click and instead gives the following error:
