Item Sets Support (Synergy)
Removed instruction that overwrites ItemInfo.Drop to support item sets.

004DB0DA CMP WORD PTR SS:[ESP+70],6 ; ItemInfo.Drop
004DB0E0 JBE SHORT ps_game.004DB0E6

004DB0E0 JBE SHORT ps_game.004DB0E6
004DB0E2 MOV DWORD PTR SS:[ESP+70],EBX ; 0
This change allows vanilla item set configuration to work properly. It’s unclear if this change may cause issues elsewhere.

Level 80 Support
Added level 80 support. Changed exp location because the additional status values overlap.
This was a major update that modified multiple functions throughout the binary to support the increased level cap.
