Yep, it happens after 92 touches. What needs to happen if a bucket isn't working is the following:
1) check if the land's scripts are turned off. Kindly ask the owner to activate scripts or reset their bucket
by respawning (rezzing a new version, not simply taking it back into the inventory and setting it back out., Do it from the original inventory item) it.
2) If your hud stops calculating your candy, take it off and put it back on. You might notice a loss in displayed total, but once you touch your
next new bucket, your count will rectify.
