Actually, update, I've figured it out!
If your save is stuck so that Rich House is broken, because trying to go with Smaar makes the game freeze, follow these steps:
1. Backup your save file. Or don't, if you're brave and/or have too much unearned trust in me.
2. Drag your save file into
You must be registered to see the links
3. Under "Variables", click the number next to #436 and change it from a 1 to a 0.
4. Do the same thing to variable #437
5. Click the "Download filexx.rpgsave" button and save your file
6. Open the save edit website in a second tab, and drag the file you just downloaded back into it
7. Double-check that the numbers next to variables 436 and 437 are both still 0
(If they're not, repeat earlier steps. Or maybe reload the page and drag the file in again; this site glitches a bit sometimes.)
8. This time, click "File Unpack" at the bottom, and wait for it to load.
9. When the text loads, hit ctrl+f and search for "3,5,A"
10. Remove the line that says
"3,5,A": true,
11. Hit the "Download filexx.rpgsave" button once again, and you should be good to go!
Now if you go to the convenience store and talk to Smaar, then the manager, and then Smaar again, you should be able to play Rich House (so long as you accept Smaar's offer the first time)!
