Reverse actors HP MP progression

Ok, i tried to run the hacked game... before the load game screen runs, the game goes wild

Check what i edited, and laugh if i wrote the codes too much wrong :
(since it's headered, the offsets are 000200 higher than normal)

0000A48C 22 13 D8 00 (JSR long to 0000D813);
PS. I use JSR long to not leave one empty byte that i don't know how to fill...

0000D813 85 1B (STA $1B (save it for now))
A9 27 (LDA #$27 (#$270F being Hex for 9999))
85 1F (STA $1F)
6B (RTL (long))


00026305 E5 FC (SBC $FC ; subtract HP 'gain' at level)
C9 00 00 (CMP #$0000)
B0 03 (BCS $630F ; branch if more than 0)
A9 00 00 (LDA #$0000 ; otherwise, set new HP to 0)


00026322 E5 FE (SBC $FE ; subtract MP 'gain' at level)
C9 00 00 (CMP #$0000)
B0 03 (BCS $632C ; branch if more than 0)
A9 00 00 (LDA #$0000 ; otherwise, set new MP to 0)

Could you find the error, please? (i think it's almost done)
