Summary
My UMG is crashing frequently. I’m not exactly sure how it happens, but I have several WBP files nested inside a single WBP, along with various variables, custom materials, and binds within each of them. I’m constantly saving and recompiling after every change I make, and it crashes randomly. These are the last few lines of my log. I looked for something similar in the forums, I’m not sure if it’s been reported yet.
