6 on the Court -- unnoticed...

10-2 SUBSTITUTE TECHNICAL
A substitute shall not enter the court:
ART. 1 Without reporting to the scorer.
ART. 2 Without being beckoned by an official, except between quarters and
during time-outs.

Also, what did the substitute do wrong? In this multiple substitute situation, all substitutes reported to the scorer, and all were beckoned by an official.

Where's the illegal act for a 10-2 individual substitute penalty?

Nobody entered the court illegally, somebody stayed on the court illegally.

You can't make up stuff as you go along.

You said the 6th player showed up only during dead balls (multiple times according your post), which mean he walked onto the court at some point. Why are players walking on and off the court and you're not noticing?

At some point you need to start officiating and quit letting this stuff happen.
