Dear @vile_Terrier , thanks for your feedback.
Regarding the issue where your screen goes black when using the vending machine in Winter Cabin, we've passed it on to our technical team for further investigation.
Regarding the issue you encountered in Nemo Kart mode where your kart stopped and became unresponsive, this may be caused by network instability.
You can enable the "Show FPS" and "Show Ping" options in the Settings → General menu, and observe the ping fluctuations if the issue occurs again.
Thanks for your understanding and support.
