I just joined yesterday and have been hosting a server successfully since then. I say successfully in that it gets up and running and players can connect, however...
Twice now I have come back to the computer to find the application closed. When I go to restart it the EcoServer.exe file in the folder is deleted. The rest of the files remain untouched and I can simply paste the .exe file back into the folder and the server loads back up fine.
I am going to poke around and see if Kaspersky is for some reason deleting it, however I wanted to see if anyone else had this problem.
We had a recent build that chrome at least identified as malicious, so it would not surprise me if your AV is quarantining it.
