Some blueprints now cause the game to crash

snek shared this bug 20 days ago
Reported

Pretty much in the title. Attempting to load certain vanilla projections now causes client and server crashes, and they stop crashing if I revert a version. Attached are player logs and the blueprint in question. This has happened with a few blueprints now, and is preventing our server admins from running certain events.

Seems to have something to do with blockrefs. One user had luck deleting all the Event Controllers, Broadcast Controllers, etc, from the grid, deleting the sbcb5 file, and then loading the blueprint

After some tinkering, I managed to fix one of my blueprints with this problem. After deleting all event controller blocks from the sbc and deleting the sbcb5 file, the blueprint loaded properly.

One fix i discovered is to downgrade back to the core systems update, paste the blueprint into a world, update the game, then replace the blueprint with the pasted version in the world. It fixes it without needing to alter the SBC files, so you can use it with cloud saved BPs. Its a little bit more of a process, but at least you dont have to reconfigure your event controllers lol

I wonder if this has something to do with the crash we're seeing on broadcast controllers where having an event controller use the random message function causes the entire server to crash

Extensive testing has been done on our (a player group's) end, and it seems the primary culprit is the Event Controller block. There appears to be some issue with loading pre-1.209 event controllers in projectors while brand new units placed after the most recent Economy 2 update appear to be unaffected. All old event controllers are also failing to load certain data, like blocks they were previously linked to for their function.


This may be conjecture, but it could be worth looking into if anything has changed with the default state of affected blocks as that would only affect previously-placed ones, and whether the game is trying and failing to load something which may have been changed or removed in that reference.

No mods just DLC. Seems random or with newer dlc. Hard to tell.
