take one id per summoned character, not one per play

Browse source 
the spawn log caught it at once: two archers took 11 and 12, and the
goblins that followed started again at 12, then the knight landed on 13.
the counter moved by one per card while a card can summon several.

two objects sharing a global id are one object to the client -
getGameObjectIndex finds the first and reuses it - so the duplicates
never became objects, never got models, and left the client and the
server holding different sets, which no checksum can survive.
