Can't rotate camera; mouse keep moving to the center of the screen

[Summer-Shen]

Hi,

On some rare occasions, I couldn't rotate the camera using my hotkeys; my mouse also kept moving to the centre of the screen. The issue is hard to reproduce, but I checked my output_log.txt and located (by time, since I quit the game shortly after the issue) a likely related error:

Tool error: Object reference not set to an instance of an object

... which suggests this is probably an issue with the Node Controller Renewal mod. The mod is one of my favourites in this game; it would be great if you could look into this issue. Thanks in advance; please contact me if you need more info.
