FTB Unleashed: Yellow screen and crash on login

[Gugmuck]

Hello,

I am running a private FTB Unleashed server in my home with a half dozen people logging on.
Everything was running perfectly until a short while ago when one person logged out (While in a mystcraft age) and had issues logging back in. Upon logging in, everything renders, shortly after which the screen goes entirely yellow. A few seconds later, the game crashes.

A short time after, we found that there were a few items missing from the game (previously placed and in use items). Logistics power junctions, a soldering station, cargo manager and cart assembler were all missing. (noticed so far).

A little bit later, I was logged on and the client froze. I checked the server and it appeared that the ftb server was also not responding and had crashed, giving me a bouncycastle.crypto error but no crash log. I restarted it, and now I cannot log in either, getting the same yellow screen and crash. Everybody else seems to have no issues (other than the missing items); just the two of us.

I have no crash log for the other person, though I do have mine. Here are the three I have received so far.

Anyone have any thoughts?

I forgot to mention, after this yellow screen issue starts, it doesn't matter what computer you log in from. I log in on mine, yellow screen; somebody else logs into the server on my pc, no yellow screen..

This issue is with twilght forest and is being worked on. You can disable TF server side and all clients to try and fix it, but I make no guarantees that it will fix it at this time. I haven't had the displeasure of replicating the issue myself to even try any fixes yet.
