How it works
Mod compatibility is determined by running Connector's code transformations on the mod jar file and validating the results. This process runs outside of the game using a dedicated command-line tool, which is part of the Connector mod compatibility checker - Probe project.
As such, it is possible that despite the jar being successfully patched, there are still remaining issues that will only trigger in game, either during startup or when loading into a world.
While we are actively trying to improve our tests' accuracy, there will always be false positives mixed in.
Reporting issues
If you find any of these test results to be incorrect, please open an issue for the mod in question on GitHub or ask our community on Discord for possible fixes.
