I seem to have trouble saving my chassis configs when playing on I76 Nitro Pack. I can save just fine when playing the normal I76, it just says "rename to save", and when I rename it and click "DONE" it says "you wanna save the new variant?" and I click yes and am able to select it. However, when I attempt to save one on the Nitro Pack, it says "rename to save", I rename it, click "DONE", but literally nothing happens, and when I click done again it just says "rename to save". It doesn't seem to matter how many times I try, it just won't prompt me to save, and this is very frustrating because I can't play on the Nitro Pack with custom vehicles unless I can save. Does anyone have the same problem or know how to fix it?

EDIT: I apologize for asking this question, I have found the solution myself. It seems that unlike original I76, you must press enter to confirm the name and allow you to save.
