I don't know if this is a bug or intentional, although it does feel to me it should be prevented.
Due to the mechanics of levequest trading, there exists a scenario where more than 8 levequests can be attempted per reset under certain circumstances.
1. Player picks up 3 leves prior for Camp X and deliberately fails them on the final monster.
2. Reset occurs, Player talks to the Leve NPC, and without accepting any leves, the failed leves can now be re-attempted.
3. The NPC offers a set of 3 leves at Camp X, up to 3 of which may be duplicates of the failed leves. For this scenario, assume the same set of 3 were offered again.
4. Player does not accept the duplicated leves, and instead returns to Camp X and completes the 3 previously failed leves in their possession.
5. Player returns to the Leve NPC. The duplicated leves can now be accepted, when taken, they replace the leves in the players inventory, meaning the player is still holding 3/8 leves at this point.
6. Player completes the 3 leves.
At this point 6 leves have been completed since reset, however the player has capacity to accept another 5 leves, meaning a total of 11 leves can be done in this reset period. Increasing the number of camps involved potentially increases this to 16 leves per reset.
However, this is dependant on the random set of leves offered. If a completely different set of leves was offered at each camp then the maximum for that reset still remains at zero.
I feel that to prevent this, the levequest trading system should be modified so that duplicate leves do not automatically replace the same leve in your possession.
