I switched over to the new bridge (unzipped, refreshed in MT4) and my Zorro instances all started displaying multiple prices in the Server Window while trading. It flicks rapidly between different assets and consistently has an exclamation mark next to it. Switching the tracked asset around a few times seems to stop the flickering but the exclamation mark remains.

I had a look at my server and it turns out MT4 is murdering all the CPUs with the new plugin, which may be related to the exclamation mark. I downgraded all of the MT4 instances to bridge 1.8 and CPU usage went back to normal.
