I've noticed a glitch when I was moving and expanding my high oven, I started with a internal space of 3 and that worked fine, when I moved I expanded it to have 6 cooking spaces and when I opened it my inventory mixed up and some of it ended up in the oven, then I crashed with a gui error, I reloaded the game and broke the controller thinking it had glitched and it still did the same, took out the ducts, still crashed, lastly I tried shortening the oven by one to make it an odd number and it worked again, so I assume even tall ovens shouldn't be done, and wanted to make sure others knew this.
It works fine now, just gives me problems if the height is even, I can live with the height being odd
