Feeding any mob with a golden dandelion is supposed to reset its age timer, as per MC-306004 .
However, sniffers are the only mob that have a non-default ageing time of 48000 ticks rather than 24000 ticks. The golden dandelion mechanic does not account for this.
Steps to reproduce
Spawn a snifflet.
Check its age value:
/data get entity @n[type=sniffer] Age. It should be near-48000.Use a golden dandelion on the snifflet.
Check its age value again:
/data get entity @n[type=sniffer] Age.
Observed behaviour
The age value was set to -24000, essentially halving it.
Expected behaviour
The age value should be reset to -48000, the usual number of ticks it takes for a snifflet to grow up.
Gameplay Impact
This bug means that it is possible to essentially halve the time it takes for a snifflet to grow up by feeding it two golden dandelions.
