Mineshaft chests are spawning empty. I have only Ice and Fire, Wyrmroost, and Citadel mods installed.

This is the error generated in the debug log it mentions Ice and fire but this error only shows when both Wrymroost and Ice and Fire mods are loading together. If I loaded each one separately they do not error. Not sure which mod is the culprit here.

Both mods (Ice and Fire, Citadel) and Wrymroost are updated to the most recent versions.

Another person posted they are having the this issue in the Ice and Fire mod Issue tracker. They also have both Ice and Fire and Wrymroost installed.
