After updating from Create 1.16.4+ v0.3.1c to Create 1.16.5 v0.3.2b, we've experienced a few seemingly random crashes on our server. The server has many Create contraptions, most of which are inactive.

Can confirm, same crashes are happening on my server.

Can also confirm, I have the same crash with Enigmatica 6 v0.5.11 (which has Create v0.3.2d and Create Plus v0.3.2.1), with the only Create contraption in my singleplayer world being a millstone, a small gear, and and a handcrank. Here's the debug.log and crash report.

This issue has been marked as stale because it has been inactive for 3 weeks. It will be closed if it remains inactive for another 3 weeks.
