For some reason, whenever I open my project, one of my blueprints changes from what I’ve saved it too.
I added two Event Graphs to the blueprint and ever since, it changes it back to this layout whenever I open the project file. What’s strange is that I NEVER saved it with this configuration of nodes, but for some reasons it changes the way they are connected together.
I make my changes (again) and save it, and for the rest of my time in the editor it’s fine.
However, as soon as I close and re-open the project, the issue is back. What’s more is that now it’s transferring into complete builds of the game. So EVEN when I do a shipping build, my blueprint isn’t compiling properly. This is monumentally frustrating because there’s no logical reason why it should be happening.
If anything, it may be related to moving the asset within folders. I was having real issues deleting some folders from my projects content browser when I moved things around, and some of those folders STILL appear in my content browser after deleting them again and again. The problem is if I delete those folders in Windows Explorer, I get reference errors when I open the project, EVEN though the folders are completely empty.
Anybody have a fix for this or experienced it? It seems to be violating the laws of sanity…
UPDATE:
A further update, after taking these screenshots I noticed that it was also re-naming the inputs on those two event graphs to just “Tick”.
I tried renaming them to “Tick In” and “Tick Out” respectively, to follow the naming convention on the other event graphs, and got an instant crash with the following callstack:

It might be worth adding that copy & pasting Collapsed Graphs also causes a lot of these crashes. Something is seriously messed up here…
