yeah Woowhat you found the easter egg, congrats. It's intentional. There is currently some ongoing discussion with the management team to launch the ITST UD Tour. (Upside Down, enough Undeads on screens this year).

Still, a tour with dead pros could be fun, rough animations and wild grunts

[edit] by the way, i a past version, i allowed to the zoom slider a wider range compared to vanilla TE, to allow setting up far cams (at lest furthest than vanilla), cause i like far cams somewhat. That may be the reason such bug can be genrated, it's a bit weird but not really troubleome or critical anyway imo [/edit]
