I came across a bug in Death Park 1. If you manage to get into an unintended spot in the main park area — for example, onto the bloody lawn in the center — the clown's AI seems to break. If he kills you while he's in this bugged state, he will completely disappear from the park and won't reappear until the next cutscene triggers. I couldn't find any info about this bug online. Would be great if anyone knows more about this or can confirm it.
