Go into the MC room, turn left, open the last cupboard door, in the lower compartment in front of the clothes is the mask.
If you play from the beginning, it will not work. I was stuck when I tried to pay her 400 bucks. Clicking on her door causes a bug. And these are the events of the second episode. Using my old save from the previous version of the game, I also did not see this episode. It remains to hope that the bugs will be fixed for the next update.
Besides the Russian Text while looking through all the cabinets, the game hoses at the point I find the mask. I hope the bug fixes happens before the next release. As is the game is unplayable to me beyond this point.
For everyone stuck on the mask, you may have to go back to your cabinet and get the mask a second time. Hope this helps!
I have downloaded the game several times from different sources. As soon as I touch the mask, I come up with this;
I'm sorry, but an uncaught exception occurred.
While loading <'Image' u'items/item_mask.png'>:
IOError: Couldn't find file 'items/item_mask.png'.
-- Full Traceback ------------------------------------------------------------
<sigh, and the language switching thing does not seem to have a resolution.>Hmmm, I never got that message. I already had the mask and had to get it a second time for some reason
[heavy sarcasm]
Yes I saw normally updates of game that have no game breaking bugs. It is normal. What is not normal is releasing updates that is not playable.
