I noticed 2x2 duplicate trade IDs in the Z12 status page and apparently resulting wrong values for current price, risk, etc.:

In the MT4 Trade window both trades are having different and unique Order IDs (1st GBP/USD: 3542722, USD/CAD: 3550943).

Any ideas how this could have happened and/or how to diagnose further?
As far as I remember, I might have experienced a crash/reboot of my VPS, so maybe it relates to a buggy Z12.trd file. Any general recommendations how to recover from such a situation - without closing all trades and restarting completely fresh?
