Describe your issue

Known compatibility issue with Petrolpark's mods. Petrol's Parts (Create add-on) and Destroy break fluids in all other mods, including Create itself and Tinker's Construct.

This issue is NOT caused by Tinkers Construct OR Petrol's Parts/Destroy themselves. Instead, it is the library mod that the latter two depend on: Petrolpark Library. Because both Petrol's Parts and Destroy require this library however, using either of them will cause the issue. The issue is only present in the versions of the library mod uploaded after 01/06/2025. As of writing, all versions after this date will break fluids in one way or another.

The ONLY way to fix this is either:

1. Uninstalling the Petrolpark Library mod (and therefore any of his other Create addons) entirely.
2. Rolling back your install of Petrolpark Library (and any of its dependents) to an earlier version that doesn't cause these issues. The latest version that I have tested that doesn't cause issues is the one uploaded on 01/06/2025. If you roll back all mods to this version, the issue should not persist and all mods will work as intended.
