V5.4.3 Interfaces losing implementation after reloading project

This fix worked for me, thanks !

Putting my Interfaces in the Content folder seems to have done the trick.

it is works! thank you

This bug still exists in 5.6.1.

A workaround that worked for me: recompile the Interface Blueprint, even if there were no changes to it since a long time.

Unfortunately you can not know until you lost your work at least once (or twice, or thrice… until you realize you’re not suffering from dementia, it’s not your git that’s faulty, your SSD is working properly, and so on…).

This needs to be fixed, please, seriously.
