v1.21 Minor Fix

Anomaly Exit

On your way home on the train, you weren't paying attention. Until you realised the train had been stopping at the same station over, and over again. Watch out for anomalies, and avoid the Anomaly Exit! Made for singleplayer and 2-6 co-operative multiplayer.

Hey all! Small fix for today. - Fixed vents not showing certain graphics correctly (this did not lead to incorrect display of anomaly, it could've looked better is all) - Fixed duplicate anomalous entities spawning - Made anomalous entities easier to pinpoint their location (you'll still need to be careful though) - Moved the Art Gallery poster down to the platform level, the "movement" is more "intuitive", and swapped it with the Bag poster As always, if you have any suggestions or problems, let me know! Thanks! ExamlGuy.
