Same issue as #97, but happens on resource reload instead of launching.
OS is Windows 10.
Using the following Fabric dependencies.

dependencies {
	minecraft "com.mojang:minecraft:19w08b"
	mappings "net.fabricmc:yarn:19w08b.7"
	modCompile "net.fabricmc:fabric-loader:0.3.7.109"
	modCompile "net.fabricmc:fabric:0.2.3.106"
}

I also have some resources in my mod which can be seen here.
dev environment log.

If you have a custom reload listener and it throws an exception without being caught on your side, the loading will hang with no error.

Annoying, I know. We should probably patch this.

Is this still an issue?

It doesn't seem to be an issue with Fabric build 127 loader build 154 anymore.
