How to get rid of BP Bug which makes BP invalid after UE4 Restart?
ich have bug in BP for a few weeks. I know it is a bug, because that could not be a BP problem.
Every time I restart the UE4 engine, my character BP gets invalid and shows error. And every time I delete the nodes and make the same connection again, click compile, and then it works. I did it at least 15 times, so I am sure I do every time nearly the same.
I startet to delete nodes, and save on every step. I deletes also folders like Binaries and Intermediate, and build and compile everything again, but the error still come back after UE4 Editor Restart. And again, and again, after delete some BP nodes, rebuild it again, and connect it again as it was, it compiles again fine. :-(
Any idea how to get rid of such annoying bug in BP?
Bug occurs after changing some already existing and in BP used struct. But as I said, even after correct all BP nodes to the new structure, the BP gets every time invalid after UE4 Restart.
Every time something like this appears:
Can't connect pins : Only exactly matching structures are considered compatible.

Open Project Settings, search for Use Compilation Manager and turn it off. Recompile, save, restart editor.
Unfortunately, structs are still deeply flawed. You can right click nodes and refresh them, this sometimes works with split structs that were updated and are causing problems or mark owning blueprints dirty.
