Potions in cauldrons going missing

Overtime, potions start to disappear in some cauldrons. It happens only to some cauldrons, while the majority tend to be unaffected. Potions never disappear completely, but just reduce in amounts. That is being followed by a visual bug – when a cauldron appears to be filled with a potion to a certain level that is not supposed to be possible, since only up to three potions can be put in a cauldron, which means that there can only be three levels of a filled with a potion cauldron. To replicate the bug, place down a dozen of cauldrons and fill them with potions to the brim. I’m not sure what exactly has to be done next, but maybe after leaving the game to run for a few hours or by leaving chunks or relogging the bug will be replicated?
