Fix for cover image bug. Warning about internal achievement reset by update.

The cover image for "Avoiding Bad Money" was an image from "Blue Puppy Adventure," so we changed it to the correct cover image. [h3] [Caution] Update will reset in-game achievements [/h3] We have received reports that the previous in-game achievements display will be initialized when updating to Ver. 1.2.0. This may be due to a change in the name of the game executable file. (The blank spaces in the file name were removed.) Achievements on Steam will remain, but if you have just started playing or are in the middle of earning achievements, please be careful and choose not to update. [h3] For those aiming for trophy completion [/h3] The trophy completion achievement, which is obtained when you have earned all achievements other than the trophy completion achievement, is not the achievements on Steam [b], but [/b], and refers to the "Acquired Achievements" on the title screen [b] in the game [/b]. When you have earned all the trophies, you will start to achieve trophy completion and it will be reflected in your Steam achievements. Therefore, if the in-game achievements are initialized by the update while you are aiming for trophy completion, please re-earn your in-game achievements, including those already listed in the Steam achievements. We apologize for the inconvenience, but thank you for your cooperation.
