Workaround is to launch with ./ as a prefix

[Cyberboss]

Even using the workaround you get an unknown argument error:

Unknown argument: ./paradise.json
[INFO] root: Server -> Starting
[INFO] cfg: Configuration loaded from file
[DEBG] root: Runtime: .NET 7.0.12 win10-x64
[DEBG] root: OS: Microsoft Windows 10.0.19045 X64
[INFO] srv: Name: MyServer
[INFO] srv: TickRate: 60(16.67ms)

Even using the workaround you get an unknown argument error:

Unknown argument: ./paradise.json
[INFO] root: Server -> Starting
[INFO] cfg: Configuration loaded from file
[DEBG] root: Runtime: .NET 7.0.12 win10-x64
[DEBG] root: OS: Microsoft Windows 10.0.19045 X64
[INFO] srv: Name: MyServer

That's RT complaining about the argument because it doesn't recognize it, despite OpenDream using it. Setting the opendream.json_path cvar instead would get rid of it.

Good to know
