Hey aliasense,

I’m having trouble reproducing this crash. Can you try reproducing this in a default Third Person Template project?

I’d also like to ask if you’re actually sending the crash report. I can’t find any crashes associated with your EpicID.

Hi ,

This is actually based on the Third Person Template but some elements had been added. Which log files do you need? Can I email them privately to you?
It seems also on our end that the crash does not happen every time, but we haven’t figured out yet when it crashes and when not.

Hey alieasense,

Logs shouldn’t really reveal anything, but if you’d like to send them privately you can upload them to Dropbox/Drive and PM me a link on the forums.

Just the project logs in Saved/Logs

Let me see if I can reproduce it. It happened a few times. It’s on Linux.

Hey aliasense-

Thank you for submitting a bug report. I have reproduced this issue and logged a report for it here Unreal Engine Issues and Bug Tracker (UE-37849) . You can track the report’s status as the issue is reviewed by our development staff.

Cheers
