I’m feeling crazy here, but I’ve just observed this happening like 8 times in a row. I implement a very simple function in an interface, it works, I save my project, close my project, reopen my project, and my interface implementation is completely empty! As if I never created it and saved it. But I very clearly did save it. WTF am I doing wrong? Or is this a bug in the engine?
Note: I did rename this function and I noticed that unrela engine sometimes crashes when I rename interface functions. Is it a crime to rename interface functions? Are there known bugs related to it? Should I just avoid it like cancer?
Observed issue Example 1:
Renaming interface functions leads to crashes in Unreal Engine 5 for mac
Observed issue Example 2:
Step 1
Implement interface function
Step 2
Rename it
Step 3
Continue programming etc, save the project completely, close the project
Step 4
Open the project, and the function contents are completely gone as if the function was left empty the entire time. So I re-implement the function.
Step 5
Save the project, close it.
Step 6
Open the project again, POOF It’s gone again! So I re-implement the function again.
Step 7
Save the project, close it.
Step 8
Open the project again, POOF It’s gone again! So I re-implement the function again.
This goes on forever until I basically either get lucky or I re-create a new interface function and just completely delete this one. I tried this 5++ times before I got it working properly.
Observed Issue Example 3:
Step 1
Implement interface event
Step 2
Rename it
Step 3
Continue programming etc, save the project completely, close the project
Step 4
Open the project, I notice my event doesn’t work. I double click it to check it’s implementation, this new event appears with a different name, I see the yellow error/warning about it’s name being different. I re-link it to the correct name, delete the incorrect one. It magically works again.
Step 5
Save the project, close it.
Step 6
Open the project again, the same error/warning is back! I have to fix it again
Step 7
Save the project, close it.
Step 8
Open the project again, the same error/warning is back! I have to fix it again
This goes on forever until I basically either get lucky or I re-create a new interface event and just completely delete this one. I tried this 5++ times before I got it working properly.
Note: I’ve never had this problem with an interface that I do NOT rename. Super weird.
