i want to set blocks back to its original block
if event-block is (cobblestone or stone):
set {_blk} to event-block
set event-block to air
wait 5 seconds
set event-block to {_blk}```
this is my code (there are way more types of blocks i want to check) and it does not work because for some reason {_blk} gets changed the moment after the wait. so after waiting {_blk} gets set to air for some reason (before the wait {_blk} is still cobblestone/stone)
