Custom match bug

Advorsus

I was checking out the bots in custom matches and came across a weird bug?

Start a custom lobby, added the bots, and choose Freddy as my killer with a single murky reagent addon for a bit more fog.

Left all settings the same except I chose Bedham preschool as the map.

Load into the match and it's sent me to garden of joy, and it looks bad. Like really bad. The sky is all static and pixelated. The entire map is almost completely pitch black, can barely see the outline of objects on the map.

I have no idea how or why it happened
