Lots of bug fixes!

Hello everybody! I was a little surprised to find so many bugs with the project. Please let me know if you have any problems with the latest upload (September 21 2021).

Here's a list of all the bugs I found/fixed:

• -fixed a crash caused by warp code running even if there's no warp object detected
• -fixed bug when loading game. The very first save had the player's state as "name_creator".
• -player now returns to main menu upon death
• -hp no longer goes into the negative
• -stopped enemies attacking dead heroes
• -possible fix for "Variable <unknown_object>.partyIndex(100395, -2147483648) cannot be resolved."
• -some NPC's didn't block player movement
• -shopkeeper/innkeeper npcs weren't being saved/loaded properly, causing crashes when talking to them
