Unknown provenance, clientside only. Server is still chugging along.

This continues to boot off all LLv14.4 clients.

Grissess commented 4 years ago

It appears to come down to some suspicious lines in ELN's SixNode core. IDEA is warning me about unchecked casts, but I'm not entirely sure which part is nulling out, or why this code has gone so far without an error like this.

I'll make it more robust in a moment and start iterating on it, but I have no way of testing, unfortunately, so I'll be coding this hotfix blind (unless someone has a consistently crashing map, e.g.).

Not so fast GitHub. There's still an issue here that we're working at. This is just a ... temporary fix.
