Quite often the same rule, or subject, is reported as incorrect due to people having assumptions about the rules. What are common misconceptions you find?
Two I get a lot:
Assuming Cutting the Track rules apply when returning from the penalty box (they don't, meaning if there's a No Pack you can hop on the track anywhere).
Assuming a ref doesn't need to issue an Out of Play warning before the penalty. Because everyone "knows" a ref doesn't need to issue a warning, they skip over the fact a Failure the Reform is issued for ignoring a warning, so one must be given. Same for False Starts.
