## Magikarp lengths in Lake of Rage have a unit conversion error
This is a bug with `LoadEnemyMon.CheckMagikarpArea` in [engine/battle/core.asm](/engine/battle/core.asm):
```asm
; Get Magikarp's length
ld de, EnemyMonDVs
ld bc, PlayerID
callfar CalcMagikarpLength
; We're clear if the length is < 1536
ld a, [wMagikarpLength]
cp HIGH(1536)

; 5% chance of skipping both size checks
call Random
cp 5 percent
jr c, .CheckMagikarpArea
