Well, the above problem was solved by getting the server from 8 days ago.
Another problem is that the quest item does not appear and cannot proceed.
(Items did not appear in `Inspect Cape scrap`, so it does not proceed.
For reference, the created character is Berserker. )
solved again,
This client can use commands. Among them, check that the item id is 30000783, and enter it to proceed.
First, enter /find item [something] and check the contents [numeric code].
Then enter /item [the numeric code of the item].
However, there is a problem that the quest cannot proceed.
Then, enter /find quest [the quest title] again and check the numeric code that appears,
Enter /completequest [numeric code].
Also, there is a problem that the connection is suddenly disconnected during the process. (When the scene of `Door of Light' appears)
Just reconnect and proceed.
+ And the problem that occurred in the first place has been solved.
However, another problem with the item occurred.
(For reference, the created character is Striker)
I created an item in the above way and assigned it to a slot, but it did not proceed.
* There is an item with a duplicate name, but after finding the top item and trying again, it proceeds.
And there are quests to get items that come out of killing enemies,
The item doesn't appear...(Or is it random?)
And the enemy is not summoned.
=_=
And what I learned while proceeding is that the quest cannot be progressed with artificially created items.
A yellow ? mark appears above the NPC, but in reality it is still unresolved. (Just like the gray [?] mark...)
Unfortunately, this can only be done using /completequest.
It's also awkward to move enemies.
Still, this level of emulator technology is great.
