On latest version (alchemistry-1.15.2-5), placing an evaporator down on savannah biome and adding one bucket of water immediately crashes the game.

Using Forge 31.1.0 for Minecraft 1.15.2

Please provide a crash log

I'm looking for a log but I can't find it. Looked in minecraft/crash-reports and minecraft/logs.
Is there any other place I should look? Or any other way to force one to be generated?

logs/latest.log should work, but only if the game crashed the last time it was open

Alright, here's the file: latest.log

And I noticed that to repro the crash, you add the water and then try and open the evaporator.

Let me know if there's any more info I can provide and thanks for looking into the issue.

That log wasn't quite as helpful as I had hoped, but could you try this dev version and let me know if it's fixed?
alchemistry-1.15.2-6-test.zip

(please unzip the .jar from the .zip file, I can't directly upload .jar files)

Tried it just now but the issue is still there. Is there any way to add like an exception handler to see the stack trace?

Perhaps try providing debug.log if it's in the logs folder

Also, try updating your forge version

Updated to latest version of forge (31.1.14), issue still there.

Here's the debug file:
debug.log

I no longer am supporting 1.15, and this should be fixed in 1.16
