Unable to be fixed. KotlinForForge explicitly casts an interface to a concrete expected type here and SpongeForge utilizes it's own implementation of an IEventBus (that doesn't extend EventBus).

There is a possible workaround but it's not clean or something I'd like to support/maintain moving forward. The whole point of Forge exposing the interface is to... expose the interface. A mod depending on the implementation of an interface to be the same isn't a smart thing to do (and this is why this issue arises).

The harder part is that the mod already made the necessary changes in 1.17+ versions of the mod, so it's not likely to get any fixes for 1.16 :/

Issue opened on Kotlin repo. Fix for 1.16 might be coming, not 100% sure

If I manage to get it working the fix will also work all the way back until 1.14.
