Summary
When using the skill Blockmask, half-blocks and barrels don't return to their original state when the Blockmask's effect time expires and the blocks return to their original state. It also changes the direction of the stair blocks and other factors.
Steps to reproduce
I made mob files that including effect:blockmask skill. https://pastebin.com/sLTfX8Py https://pastebin.com/HAjTuiMW
then I ran the server and battle against this mob in area placing some block added in 1.14.
Current behavior
When using the skill Blockmask, half-blocks and barrels don't return to their original state when the Blockmask's effect time expires and the blocks return to their original state. It also changes the direction of the stair blocks and other factors.
Intended correct behavior
I think the previous block should appear after effect:blockmask skill.
Server log file
The latestlog is attached.[Legacy attachment omitted]
Debug log snippet
There was not.
Proposed fixes
I think that may caused by no packets were sent for the block.
