[1.12.2] Rendering issue with Multiblocked + AE2

[TheComputerizer]

This is a bit of an edge case, but I use the assembler for a custom multiblock via multiblocked. The issue is that the renderer plugin for JEI (or HEI in my case) fails to register for that multiblock when AE2 is installed since the Assembler tries to call ApiGrid#createGridNode on the client side as can be seen in this error. I assume AE2 has reasons for not allowing that method to be called from the client, so it would be cool if a client side check were to be added to the Assembler for that.
