If a sale is created manually in OTTO and a price update is triggered via magnalister before
the next synchronization, the offer may be removed.

Background:
OTTO synchronizes inventory data, including offers, only once per day with the magnalister API.

When performing a price update, OTTO also requires that all price fields be fully included in the
update request.

If the current sale information has not yet been transmitted to magnalister at that point,
it cannot be taken into account during the price update.

Recommendation:
If you create sale prices manually directly in OTTO, please wait for the next daily synchronization
before triggering any further price changes via magnalister.

Important:
This behavior affects sales created manually in OTTO if a price update via magnalister is performed
between the creation of the sale and the next daily synchronization.
