I just updated our Server to Spigot 1.21.4 using the BuildingTool. We were exited to play with the new features and everything worked fine we searched for a pale Forrest. When we found one of course we wanted to get so of the new creaking hearts. so we waited till night for the creakings to spawn and locate the hearts. But when we hit a Creaking the server crashes and the console shows that a error with the particles that should be sent by the creaking to the heart was made and could not be processed. Would be nice to get this fixed as soon as possible because i still managed to get some hearts to place them near my base as prevention for thiefs. But i have some funny friends who like expoliting this and crashing the server on purpose.
