I am very sorry for not responding earlier, I did not see a notification. Similar things to what you are describing is currently happening on other widgets as well (5.2, UEditableTextBox). > [Bugs bugs bugs] Slate widget synchronization - #3 by Roy_Wierer.Seda145
I don’t make engine modifications myself. It’s EPICs job to not make a mess of their releases because we all suffer from it. No one can make marketplace products for a custom engine version which only few people might use. We have to wait for a fix from EPICs side on a next release, or in the worst case stick with an older version for a while.
