This video would have been made a lot sooner, but I was having some considerable difficulties with OpenShot. I was making a video with HidDes, Corruption Cards and Warm Reception on the mapset Kuchitsu (inspired by Mr Icarus's somewhat recent stream). As it likely turns out, setting Warm Reception to delete monsters at the spawn area deletes the DERP when it was deployed (I think because it technically counts as spawning, with WR only checking Decorate/ZScript actors when they spawn and not checking if they are friendly or hostile). Hence this video!
