[0.15.19] Game Crash on Mutiplayer Blueprint View-Deletion

[jsharkey13]

In multiplayer games, the game crashes for player X (on both Mac and Windows) if player X is mousing over (viewing details of) a blueprint owned by player Y in the shared library whilst player Y deletes it from their blueprint library. It does the same thing for blueprint books too. If player X has the blueprint open, the game does not crash; nor does it crash if player X is merely viewing the library. The crash only occurs when the mouseover preview is open.

It is map and time independent, and reproducable every time. This was on a map running on a headless server, which may make a difference.

If player X gets to the screen above, and player Y then deletes the "Copper Wire" blueprint whilst the preview is open, the game crashes for player X.

Was this a typo or is it really version 15.9?

Definitely a typo, thank you! (0.15.19)

[Rseding91]

Thanks for the report. It's now fixed for the next version of 0.15.

[jsharkey13]

Great, thanks! It was such an unlikely set of circumstances required too.

Keep up the incredible work!
