The 5th night is of interest in this replay.

I, #13, bussed myself with #3. #10 attempted to roleblock #3. I did not get the message that I was bussed and neither did #3, however, #3 ended up being role blocked. Is this WAD or is it a bug? Replay available below.

13: 13+3
10: role blocked 3
13 and 3 did not receive messages that they got bussed
3 was succesfully roleblocked, however.

I've read that the game repeats the swapping process a number of times to deal with paradoxes. It might be related to that mechanic, in which case it might actually be WAD. However, shouldn't we have received messages confirming that we were indeed bussed, or shouldn't both of us have received messages confirming we were role blocked?
