[v10.5] Errors occurred while trying to remove task from queue

Summary: While trying to remove a task from a work queue (click-dragging task tab down to trash tab), several errors messages appeared and the attempt to remove the task in question was stopped and the task tab returned to its place in the crafting queue. Upon trying again, the task was successfully deleted and no additional error messages appeared.
Frequency: Highly infrequent. In the space of 5 hours of gameplay, this error only occurred once.
Impact: It seemed to have no additional impact on workers or the other tasks within the crafting queue.
Attachment: The top-most error box
