For whatever reason, in any game on MCC, when using mouse and keyboard, I can’t press E to move to the right while crouching. It works fine in every other direction and works with my controller, though. I only noticed this on the most recent update. It works when bound to any other key, just not E, which I don’t have anything else bound to.
EDIT: Restarting my computer entirely resolved the issue. The moral of the story: troubleshooting 101 usually works, lol.
