'Unable to change order' question

[shortrader]

Hi - this morning my strategy returned an 'Unable to change order' error and subsequently shut itself down. I've run this strategy for weeks on real time simulator and also in Replay without incident. Of course, on live trading, it chokes (on a profitable trade, no less). My question is - will a Change Order fail if the requested change price is the same as the live order? I see in the log that the change order was submitted roughly 6 minutes after the original successful limit order (which was correct). The order state goes from 'Accepted', to 'Working', then fails. The live market price was over a full point away from my limit, so the order wasn't in flight. The only thing I see that is suspect is that the requested limit price is the same as the live, working limit order. I've confirmed that my code 'could' let this happen in certain circumstances. I'm using unmanaged approach in NT8.

Any thoughts?
