Item filter bug with advanced unique mod range filter

Hi everyone,

there’s currently a bug with the item filter advanced unique modifiers. At least 100% reproducable with the unique ‘Tempest Maw’. Reproduction as follows:

  1. create a filter to hide all uniques

  2. create a filter above that which only shows ‘Tempest Maw’

  3. Save-> drop Tempest Maw->should be shown

  4. Edit the tempest maw filter entry

  5. In the properties click ‘modifiers’ that should open a window to filter the affix ranges

  6. click parent node (Tempest Maw) so everything is checked

  7. click parent node again so everything is unchecked

  8. update filter

  9. in step 3 dropped Tempest Maw is now not visible anymore

Has to do with the -X Totem Mana Cost mode. In the filter xml the value for is set to true. If we manually in the xml set this to false and import the filter it works correctly again.
I was not able to reproduce that with another -X to X mod yet. Perhaps only an issue with this explicite totem mod.

Thank you
Regards
