Hey, sorry but I cannot. Since this wasn’t a showstopping problem for me I just kept working without compiling from the BP window and eventually it went away. I ran into the same error a few times but worked around them the same way.
Unfortunately at this point even if the error happened again, my blueprint graph has become pretty large and I don’t think I could post it without spending 40 minutes stitching together images unless you only needed a portion of it (or theres a better way to output a picture of the BP graph that I’m not aware of?)
