Structure Pins disconnect after reloading project (BP Library)

Development Programming & Scripting
1

Hi there.

This is more an FYI instead of a question. I’ve red several posts about disconnected pins of structures in widgets after reloading the project. Occured in 4.12 I believe and was fixed in 4.13. However I discover the same issue in a Blueprint Function Library in 4.15.1. Every time I load the project, the structure output and input pins are not connected anymore.

Please tell me if I sould upload a demo project or screenshots. (I thinkt they aren’t necessary because the issue is known and documented in widgets as I said before.)

Same here, when I have arrays of structures created from editor (they disconect when I restart the editor, and they also drop cooking errors).

And I’m also using the last version (4.15.1).

One example:

thank you for your input and the screenshot.

I discovered, that after connecting the pins several times, saving the project and reopen it, that the pins stay connected.
I would not say that this is a solution but I guess it gets trickier to reproduce the error or “bug”.

Yeah, I notice that sometimes it gets fixed when you work around with other stuff, but then it came back again (in the same spots on in some new ones).

Right now I still have those issues. It’s not so bad to plug them again and again but the big issue came with the cooking process, it doesn’t work because of this problems.

Hope we can get any answer from Epic. I also started another post with the cooking errors included, but there was no reply either. Here:

Yeah I also had this problem but it got resolved quite easily for me. Try delete the node, save and compile, readd the node, add some other nodes, save and compile. That might resolve it. I remember I did something similarly.

Thanks for that but unfortunately I’ve just it and it continues the same way :S

This is so weird, but I found a way to temporary fix it. Just renamed the structure which was making troubles, “Fix Up Redirectors in Folder” (right click on the ■■■■■ with the structure): that was just in case, save everything and restarted the editor.

Now it doesn’t unplug the nodes and (most important) it also compiles during cooking. And yes, I was able to rename back the structure, and after restarting the editor once again it continues working well.

Again, it’s weird, it’s a bug. Hope we get any answer from Epic, because this is not the first time I have this kind of problems with structures and nodes. At least now we have some walkarounds here :slight_smile:

This problem does not occure in newer engine versions
