The Utimate Company DW that running FGO is one of not so good reaction sample.
The game encounter some completely crash or data disappear problem.
It cause DW to close for maint up to 12 hrs.
When they open... they only compensation 10 gems.
And you can guess... many hate-speech flew around their tweeter.

If you search for Nutaku Jp ver. you found at DW office.
