Dedicated servers will crash what seems like randomly when selling things using the shipping bin, client doesn't crash. Attached are the 2 latest crash logs both giving a "java.util.ConcurrentModificationException" error. I attached two to hopefully be of more help.

If you are still experiencing this crash after updating to HarvestCraft 1.12.2L and Forge 2555+, please re-post here: #127
