The title says it all. I hate making a thread to address such a trivial issue but I didn't want to see the error missed for the next update. Aluminum is currently spelled as aluminium in the game. When using console commands, it will be confusing for many.
As a second suggestion, maybe we could have a sticky thread for minor bugs/spelling errors such as the one I've pointed out, so that we don't need to create a thread to address small issues. It doesn't matter to me, but I feel like I'm cluttering the boards with my threads.
