while playing multiplayer with a few others (18-20 people) on the "explosive 48 hour game" that is on the newest version.
i was downloading players blueprints and books and when i previewed one of the books it crashed, i don't know if you could reproduce this because there was a lot of players and a ton of blueprints.
it was a science book with 5 prints in it and when i hovered over the production science it crashed.

Thanks for the report.
Finally figured out where the problem was (the crash dump and the information you were previewing blueprint book of other player was very helpfull, thank you).
Fixed for 0.16.21
