You say you have a bug, but you didn't describe what it is.
If it is restarting when you are near the two batteries in the rift, check this thread.

If you have hit a different type of bug, contact Support. Be sure to give the details of what is occurring, WebGL vs. Mobile, etc.
On your game screen, choose the Settings wheel in the upper corner. Write down your Player ID and then choose the Support button. Scroll all the way down until you see a list of categories. (Do not use the white text box!) Choose a category and then provide your Player ID, and problem details.
