• Fixed entity rotations during //revolve to be more consistent across all entities
• Changed blocks without legacy ID/data values to return -1 in expressions, to allow differentiating from air
• Fixed entity home positions not being updated when pasted
• Fixed cases where the experimental snapshot mode may erroneously close a file too early, causing errors on usage
