Bug fixes

List of changes (mostly bug fixes)

• Could enter Pametrice's house from the north
• Interacting with vendors *rarely* caused the game to crash.  Root cause still unknown, but I put in a workaround
• Repeatedly opening/closing the load menu from the main screen made the menu drift
• No clipping in Zemi's house made you unable to leave
• When a certain character hit level 20, examining their skills made the game crash
• When Zemi tells Pech she'll introduce him to the villagers, it wasn't clear this included the 2 outside the village (Rip and Hunt)
