It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

Re: I2C Slave: how to generate NAck ?
Well as I read it, the only time a NACK is sent for valid data is when the Master is requesting a sequential read. The Master sends a NACK on the last read to say he is done. But there is no reason why the Master couldn't ACK the last read and then send a STOP. Also note that the NACK/ACK is sent by the master on a read, not the slave.

After the last data byte, a NACK is sent by the
Slave to the Master to indicate that no more bytes
should be sent. After the NACK pulse, the Master initiates
the STOP condition to free the bus.
