Currently there's a major issue that makes some nights unplayable, however, follow these simple instructions until the next update is out (Don't worry, it won't be long)

What's happening is that, the night doesn't end at 6 AM, even with Ringmaster Foxy disabled. However, that's what you need to take advantage of. Since his ticket price is dependent on his AI, this means you can set him to 1 AI and he'll hardly be a problem, since his ticket only costs 4 remnant at 1 AI.

So, in conclusion, until the next update is out, ALWAYS play with Ringmaster Foxy at at least 1 AI, buy the ticket, and you can go along your normal playthrough.

Really sorry about this! I promise it won't be long until the next update, so hang in tight!
