And notice that it will only caused in the local.
Because it will be packed into single dll in the release build.

[andy840119]

Not a big deal, just annoying.

[andy840119]

Not really sure will it be a good idea to place something like FakeRuleset in this repo?
Anyway, the FakeRuleset will not be found in the release build, i guess?

See RulesetStore in the osu.game

{
    LoadedAssemblies[assembly] = assembly.GetTypes().First(t => t.IsPublic && t.IsSubclassOf(typeof(Ruleset)));

catch (Exception e)

    Logger.Error(e, $"Failed to add ruleset {assembly}");
