Actual behaviour:
Table cell "My bid" content changes to "no" for a won auction and any already known future auction that completes an associated auction group condition if such a condition is involved. This probably is an internal consequence of deactivating all related auctions. You see that the successful bid has been deactivated after the auction completed. This does not happen for auctions that are not related to a group.

Expected behaviour:
Table cell content may change to "no" for future group auctions that are actually disabled by completing the group condition. For any auction that successfully participated in completing the group condition, the table cell content should stay the previously set amount, like it is for any other won auction as well, and like it is in the single auction detail display window. This probably would be achieved by deactivating only these snipes of the group that haven't already been successful, and leaving successful snipes active for group related snipes like they are for non-group related snipes.
