I have a map called TestMap. I was running my server with a command-line option to load MainMap. Everything worked fine but I was getting an error “Failure to enter /Game/TestMap”.
The thing is, the problem was that MainMap wasn’t there. I see another error in the log saying it can’t find MainMap but that wasn’t displayed as red error text like the one I did see.
That led to a bunch of confusion until I realized I had reused an old batch file and the command-line was there. Removing that got rid of the red error message.
Seems to me that this isn’t ideal so I thought I’d put it out there.
