Downscale core nodes

[alexa22013]

When I downscaled core nodes from 3 to 2 the repicant nodes were crashing

replicant node logs showed this error
[emqx-replicant-6d5577f77d-lx4: 2023-02-26T19:08:47.518993+00:00 [error] line: 182, mfa: mria_lb:list_core_nodes/1, msg: mria_lb_core_discovery divergent cluster, node: '[email protected]', previous_cores: [], returned_cores: ['[email protected]','[email protected]'], unknown_nodes: ['[email protected]']]
how to avoid this?

Also is there any practice on when to scale core node and when to scale replicants?
