The client raises this error when retrieving the entity, and nothing syncs anymore...

But I can see the stored value with graphQL and sozo model, but balance_a doesn't look correct, it's padded with ffffffffffffff:

$ sozo model get pistols-ChallengeFameBalance 1
{
    duel_id         : 0x0000000000000000000000000000000000000000000000000000000000000001,
    balance_a       : 0x00000000000000000000000000000000ffffffffffffffe4e51b291d10b00000,
    balance_b       : 0x00000000000000000000000000000000000000000000001b1ae4d6e2ef500000
}

Expected behavior

Torii client should retrieve the negative value.
