On attempt to overwrite automatically created function on child blueprint engine crashes. repro: Create timeline in actor class blueprint, compile. Create/open existing child of this actor blueprint. Find automatically created function in overwrite section of child blueprint which called " %timeline name% Finished func " or “%timeline name% Updated Func” Click to overwrite - engine freeze for eternity. I guess thats should be automatically created function for child, but it dosnt work. /edit/ [added screanshot](http://puu.sh/kjBL2.png) ---

Hi , Does this occur in a clean, blank project with no additional content or is it limited to one project? Additionally have you tried this in a 4.9 project to see if a fix has already been implemented? Do you have any crash logs that I can look at to see what may be occurring? Have you checked to see if your memory is spiking when this occurs by opening task manager and watching your UE4Editor.exe process while performing the actions listed above? ---

4(dot)8 - global ram usage go to 95% instantly, but actual ue4editor exe is growing really slow, no CPU freeze and no report. 4(dot)9 - instant crash, no report info besides machine and client ID “No minidump found for this crash.” ive send this blank report with additional info “timeline, inherit automatically created “%timeline name update func” crash” also updated first post with a screenshot of those automatically created functions /edit/ for some reason 4.8 and 4.9 was changed to 1. and 2. by answerhub himself. ---

Can you send me a sample asset that this is occurring in? I have not been able to reproduce this on my end thus far. ---

Hi , Unfortunately I’m not seeing any crash on my end, it doesn’t produce the %timelinename% function, though I do get a variable for the timeline, no errors or crashes occur when I interact with it. Are there any additional steps I can take that may reproduce this on my end? ---

Hi , I was able to reproduce this and have entered a bug report, UE-21434, to be assessed by the development staff.
