Is it a bug (I guess)?

I ran the command changelevel 1v1_test and then I got the map running. I could only see the minicard - everything else was black. I went to the menu and went into hero testing with the same command, and this is what I got. If you restart on the same map the effect persists, it only disappears if you go to another map/restart the game.

Old maps run on old shaders that are no longer used in deadlock.

If you want you can use -dev launch command to see them full bright

Otherwise you can't see them.

There's not much to fix other than them re-rendering the maps with the new shaders, but I dont think they plan to do that since the maps are no longer being used.
