At the time of this crash i was afk, so unsure of anything occurring prior to the crash.

In this case, it appears to be a Storage Drawer issue. (based on the provided world/pack)

What happens is that the interface tries to store 1x nether star into the network, which end up hitting a storage drawer and then being returned 130k nether stars as left over. At which point everything breaks down.

So nothing we can really fix, but I will look into crashing way earlier. Essentially crashing immediately when hitting a broken IItemHandler (more remaining than ever inserted or more extracted than requested etc). At least to avoid bubbling up and obscuring it. Reporting the actual tile entity is probably impossible, but at least mentioning the FQDN for the class should help.
