Crash with blueprint book MP interaction on: "BlueprintBookHeader::getRealLabel"

[cybersteel8]

My mate and I were messing around with the new blueprint section and managed to cause desyncs and crashes. Here are our crash logs.

I just encountered the same issue.

Situation: Was in multiplayer playing with new blueprint screen, saved another players blueprint book to my inventory. I had moved a blue print that was in the book, out of the book into my inventory and then I right clicked the empty book to rename it. Unable to recreate the issue as the Game crashed, and I've been getting issues reconnecting to the server. Only I have issues connecting, other two players have no issues.

Attempts to solve:
1) Server restart did not change situation.
2) joining single player game then trying to connect to server did not change situation.
3) downloaded the save file, tried to open it in single player, did not change situation.
4) delete attached below save file and reverted to earlier autosave. worked as intended.

Server Log, Local Log and Save File attached.

Here is the current-log

The crash first occurred when opening the blueprints menu with 'B'. Reconnecting to the same server causes the same crash immediately on connection.

Occurs on 0.15.2
No mods were used.
Default settings on fresh zip file.

Just leaving a note here that I still have the same crash in 0.15.2.

I think I have the same bug(my description would be exactly the same) on a different platform. I was able to reconnect to the server after some time though, so it might be related to some players and their blueprints present on the server when blueprint window gets open with "B"(or it is already open when you reconnect). It seemed that not all the players get crashed, so I was wondering if it was system/OS specific. I am running Linux and my setup looks quite different from the post above, so I hope my log will be helpful.

P.S. Same thing was happening in 15.1 and I read the 15.2 update and thought it was fixed(some crash due to blueprints sound very similar). Still present in 15.2.

When i join my friends server my client crashes after downloading the map.

A workaround I've found is to join as an entirely new player by changing your name and joining the server. Since the server does some serverside saving of information based on your character name you'll start with a new character but you can join sucessfully.

Hi, thanks for all the reports.
I believe this is fixed in 0.15.6. Please let us know if you get more crashes in current version.
