Not exactly sure how to replicate this but happens after some random time on a mass multiplayer server

Crash report from a user on the same server and crash: viewtopic.php?f=7&t=117689
The user above didn't know we would post a crash report and his crash report is probably unrelated to the actual reason of the crash.

Got another one with SIGSEGV seems it might be something with null pointer or undefined pointer

Code: Select all

if it is then the first one was probably me. i tried to paste a nuclear blueprint when i was on around 5pm ish i think ( when you posted the report) and immediatly after the whole world froze and i got server not responding error. this happened again on my private server with friends this evening which i why i think this may have been me.

idk about that second crash though?
maybe some other blueprints have the same bug


this is the offending blueprint string

I doubt this is linux-specific, and without an exact reproduction there isn't much I can do. I tried placing this blueprint in multiplayer and it worked fine.
