Version 2.3.29 with "Default" Point Account, and a "default" item pool. "Simple mode" is enabled.
If I use the API to add a new event, it is created successfully. However, the site shows no point account or item pool.
If I use the API to retrieve the list of events, that same event shows that it does have the defaults.
My workaround has to be open Event Management on the website, Edit the event - and clicking Save without making any changes. It then appears to be correct.
In the API add_event I have tried various values for "event_default_itempool", including leaving that property out altogether with no change in this described behavior.
The reason this is a problem - I cannot seem to manually add items to any raids associated with this event until I fix the event through the website. I can add items via the API but not manually through the website.
