Are you looking for discrepancies or bugs as-is?
 

For instance, some quick ones based on the baldio patch note archive that may or may not be on green 99 (working on getting to a point of testing them)

- Summoned food/water should not disappear when logging out (until the september patch)
- Necro healing spells should not have a 12 second recast timer (the patch note explicitly mentions screaming terror boosting them as a class ala mesmerize in exchange for no longer being a "massive group healer")
- Summoned items kept in a bag in bank should not disappear when player logs off

I did confirm my summoned water disappeared after remaining logged out for a bit (it should persist until 9/22/99 patch).
