Known Errors: Bugfix provided by Einar Saukas and Bandit:#

• The game cannot be completed because of a bug which prevents the gun being discovered in the circus. The problem is that it was originally written for a "Quill A" database but converted to a "Quill C" database (presumably so that it could include Illustrator graphics). The gun discovery sequence is controlled by flag 28, which is reset every turn since it became a reserved flag in "Quill C". This problem can be solved reusing flag 21 (that controls finding the jar) for the gun also, since the jar is a requirement for accessing the gun location. Both cases are originally implemented as follows:#
