❗ Checklist

• I am using the official english version of Slimefun and did not modify the jar.
• I am using an up to date "DEV" (not "RC") version of Slimefun.
• I am aware that issues related to Slimefun addons need to be reported on their bug trackers and not here.
• I searched for similar open issues and could not find an existing bug report on this.

📍 Description

When trying to use the advanced industrial miner, it always uses up a lava bucket (The fuel) and just breaks. The pistons don't move which indicates that its not searching for ores to mine and let alone it doesn't mine anything even though there are surrounding ores , but for some strange reason when I right click the blast furnace it tells me that the machine is still running. I've tried restarting my aternos server, changing the machine's location both in x and y manner but it still does the same. And before it completely freeze, it uses up the lava, the pistons move and then it pretends that it mined an ore before completely freezing and breaking.

📑 Reproduction Steps

1. Just build the advanced industrial miner normally...

💡 Expected Behavior

I expected it to work and mine ores 11x11

what version of Java are you running?

Please provide full log, current one doesn't tell anything.

what version of Java are you running?

On aternos its java 8, on my computer it's version 16.0.1

Aternos should provide that for you.

The error looks like it was a java command that's for a more updated version of Java. I would update to Java 16 or 17 if possible.

Aternos should provide that for you.

I just Updated my java right now, I have the latest 1.8.0
I'll just now

1.8 is not the latest. on the server you need to run Java 16 or higher. 1.8 is also known as Java 8 which is an old version

Slimefun does not require Java 16 (yet). The issue is that Slimefun is using API that was only added in 1.16.5, so you are probably running minecraft 1.16.0 - 1.16.4

Since you guys recommend and I'm a moron, send me the link to download it please, thanks!

im typing about that lol.
you are using 1.16 version below 1.16.5, and getMinHeightonly exists above 1.16.5

So Ill just update my minecraft to 1.16.5 and get java 16 right?

no need to get java 16, but we recommend it

It finally works, guys thanks so so so much!
