Ignore as the mod works as normal in actual play

You shouldn't ignore them since the compilation errors are the direct cause of the crash.

This isn't an issue with the mod, it's an issue with your project setup. The lines you're referencing are supposed to point to GuiInfoPanel from Tinkers' Construct, but instead are pointing directly to GuiContainer from vanilla, which is abstract and thus cannot be invoked directly. You can try to go directly to which method super is calling to verify. I'm not sure why this is the case, but something is definitely off here.

Before making any future issues on this tracker during your development process, please verify first that the problem is also present in the official production version of the mod.
