Discovered a repeatable error while in the Red Zone area of the latest version. While in the street view simply advance the time from Evening to Night and this CtD happens:
File "[gamedirectory]\itch.io\campus-confidential\CampusConfidential-0.42-pc\renpy\script.py", line 1103, in lookup
raise ScriptError("could not find label '%s'." % str(original))
ScriptError: could not find label 'shops_sex_front_dialogue'.
Windows-10-10.0.19045 AMD64
Ren'Py 8.3.2.24090902
Campus Confidential 0.42
Granted you normally would never advance time while in that area, but if you do the game crashes. If you go into a shop, advance the time, and then exit back out to the street the game does not crash.
