1.20.1-Accessing LegacyRandomSource from multiple threads

[gdrfgdrf123]

I am developing a mod about block entity rendering in forge47.2.0, but I encountered an inexplicable bug that I cannot grasp the rules at all. It sometimes triggers frequently and sometimes not at all. What should I do?

You’re probably calling level.getRandom() somewhere, likely on the client side. Either use a living entity’s random, or the random that’s passed in to the function of one of your block’s animate / tick functions
