It may happen because the MC is hitting both the notebook and bed trigger at the same time, since they are really close....There is actually a bug with the sleeping menu on the bed, maybe It also aplies for the computer menu, as the code may be similar. I cannot remember the trigger really well, but It is something like walking away from bed with the menu still open, or away from the computer, for example.
The menu in question becomes un-interactive, It cannot be closed and neither you can click in any option. I solved the bug by interacting with the bed again, then the options on the menu were duplicated, I had 2 sleep buttons, in this instance. Then I proceded to click on the X, wich I only had seen one, different from the other duped buttons, and the whole thing closed. The game worked normally after that.
I'll check it. Thanks!
