Yes

CTD? This is a NPE (NullPointerException) while retrieving the tooltip data. This is caused by an external mod.

Ah, I think I have figured out what is causing the issue. We uninstalled SuperCircuitMaker from the server, but I forgot to remove it from my client. The crash occurred after clearing the crafting grid's crafting inventory of one piece of redstone dust, which displayed the recipe for tiny redstone dust, even though that item did not exist on the server. I think this may be an issue of information mismatch.
