I keep seeing nonce errors in the poloniex API. I thought they were harmless, but it seems the bot's missing a few orders or falsely thinking they've completed. For example:

2017-11-29 09:27:02  0.0598700 DASH-BTC   +0.01%        4   63 ++     0000.06  0000.06   buying  0.00000000 DASH  0.06270364 BTC   +0.00%   -1.79%
2017-11-29 09:27:39 - 0.05958267 vs our 0.05958260

2017-11-29 09:27:39 - cancelling order

2017-11-29 09:27:40 - buy order timed out, adjusting price

2017-11-29 09:27:40 - placing buy order...

2017-11-29 09:27:41 - buy order placed at 0.0595827 BTC

returnOpenOrders odd result:

In reality I still see the limit order as "open" in poloniex. I saw a few threads on something similar, the main suggestion being "create a new API key". I did so, but this remains present. Has anyone managed to come past this? It seems to be affecting performance.
