I am unable to connect a Cloud device that has one or more VMnet interfaces numbered greater than 9. GNS3 console error:

Server error [-3200] from 127.0.0.1:8000 SW1: unable to create generic ethernet NIO

I can see all the VMnet interfaces from Powershell:
PS C:\Windows\System32\WindowsPowerShell\v1.0> gwmi Win32_NetworkAdapter | ? name -like '*vmware*' | select Name

The .gns3 file list the adapter above 10:

I just noticed the config for VMnet10 is missing " "nio": "NIO_Generic_Ethernet", "

Beta 3 allows VMnets above 9 on Windows.
