Ever since the update that allowed ultra-heavy weapons to break shields came out, other weapons such as axes and modded weapons that are supposed to disable shields are completely unable to. Turning ultra-heavy weapons disabling shields to false in the config just made it so that nothing was capable of disabling shields.

Just wondering if this is an intentional feature or a bug that has plagued my server's modpack for the past few seasons? If it is a bug I'm assuming it's related to our modpack as I can't find any other issues here talking about it.

That's a bug actually! Crazy that no one has pointed it out yet, was caused by an oversight when I implemented the config for whether ultra heavy weapons could disable them or not. Will fix that!
