SX 900 Bug? TX Status=MAC ACK, but 20ms later RX Indicator is valid.

Is this a bug?
Using XBee SX 900 FW 900A in API mode 1, TO=0x40 (multipoint)

I am seeing RX Indicator frames directly following a MAC ACK Failure TX Status frame.


Time (ms) Description
0 TX Request; direct address with unique Frame ID
65 TX Status - validated Frame ID; delivery status = 01 - MAC ACK Failure, retries=RR
88 RX Indicator - validated direct address and Frame ID - see above ^


This is something that you should send an email to support about. Make sure that when you do, you include everything needed to reproduce it. Also include all of the frames you are seeing.
