Description
# Overview
A simple Immersive Engineering addon to backport critical bug fixes and minor content to 1.20.1.
Note that in some cases I am not the one who patched these issues, BluSunrize (and the IE team at large) is. I merely backport the fixes to 1.20.1 with permission, so the IE dev team can pursue their goal of focusing on new versions of Minecraft. Elsewhere, I and other contributors have written entirely new fixes that don't rely on IE's code. **Do not** be annoyed at Blu and co. for not implementing these fixes themselves, as back support is time consuming and difficult for a project of IE's scale.
**Currently Supporting:**
_Fixes of reported IE problems:_
Fix: issue #5906: Fluids no longer destroy multiblocks.
Fix: issue #6149: Arc Furnaces give the correct percentage of secondary outputs (was previously inverted).
Fix: issue #6305: Coke Oven Exploit
Fix: issues #4917, #5440, #5909, #5933, and #6203 about logic errors with the Diesel Generator. Diesel Generators now don't confuse water for fuel, don't run infinitely, properly consume the right amount of fuel, and more. Read these issues on IE's repo for detail (or check the issue on my repo to find hyperlinks to each of these issues).
Fix: issue #6205: ear defenders not working.
_Other fixes:_
Fixed dark triangle-shaped patches appearing on machines under normal lighting
Fixed parts of machine surfaces rendering inside-out or invisible from certain angles
Fixed machines showing outdated/stale textures after reloading resource packs via F3+T
Improved rendering performance: large machines no longer draw the same geometry up to 7 times over
Have some features or fixes you'd like to see in 1.20.1? Please let me know via the Issues page on the repository or my discord [here](https://discord.gg/mZUjrWK6NF).
