there is a bug in D.I.E. that makes you crash when you open a chest, Sometimes, my chests change, from double chests to 2 small chests next to eachother, for some reason, but whenever i open one of em, they both open and my launcher closes immediately, this only happens when come back to my base, after being away from it for some time
Unfortunately this is an error in TFC itself and there is nothing we can do about it. It's strictly clientside, so if you see that and relog 99% of the time that fixes it. TFC Devs do know about it and have done some work on fixing it, unfortunately it might be an update we may never see due to some forge compatibility issues.
