I feel quite excited. I found what needs to be changed to activate nigh infinite random encounters. If someone is interested I can put "fix" here (it requires quite a time to change numbers for each and every zone, and it is quite spoiler'ish, so I'd rather finish game first). There is only 1 !but! - you might want to start game from scratch, "fix" might not work for old save..

Fixed encounters won't respawn.

I attached partial fix for few locations. If someone wants to test - amount of encounters in all those locations was increased by 1 billion:
1. Rat Cave.
2. Velegarn's Beach.
3. Sporia Forest.
4. Sorrentia Road.
And a couple other locations.

Just rename attached file into SOL.jxrul2 and copy it into game directory (make back-up of original file first!).
