figured you use append array, but maybe remove option to add arrays together, or give an error instead of a crash

Hello Bennetherwood,

I am attempting to reproduce this issue, but I am not getting the same results. I am in 4.4 and here is what I am trying to do:

13888-addarray.jpg749×275 34.6 KB

In the screenshot you can see that I get an error message, then the pins do not connect. Once I let go, the link is not made, but nothing more happens. Could you let me know if there is anything I am doing differently?

Also, please provide us with the .LOG and .DMP files from your [project]/Saved/Logs folder. Additionally, you can please send us the CrashReportClient.log file located in C:Program/Files/Unreal Engine4.0/EnginePrograms/CrashReportClient/SavedLogs.

Thanks,

i think it was the other way around which caused the issue, with roll5 connected add roll2, wouldthere may be an issue with giving you the Blueprint because using the BP later in the day i got a major issue where doing anything to the BP even opening the BP caused a crash, so i have a few crashes not related to this :frowning: so i had to get an older version from backup, additionally ive likely had a crash/2 before when trying to test my system to the max, how do i find which .log/.dmp/crash report you need?

IVE JUST DONE IT again … you do the roll5 pin first and it causes a crash for me at least and ive got all the files now because i know they are connected to crash
:smiley:

(i cant upload the .log and .DMP files as its not a valid attachment form for this forum) how do i upload them? do you have an email to send to man?

Hey, bennetherwood.

I was able to reproduce this crash on my end, so I’ve reported it internally. We’ll assign someone to it and release a fix when possible.

Thanks,

Jonathan
