[2.1.17] Crash (FluidBox.cpp:432: !this->buffer was not true)

[protocol_1903]

I'm experiencing a weird CTD with editor mode and the mod I'm working on, particularly it's the "instant blueprint building" setting. I'm going to keep digging around with the cause on my end, I have a feeling it's trying to do fluid something with an entity that doesn't have a fluid segment, possibly a ghost or an entity with no connections.

1. Load vanilla factorio 2.1.17 with the attached mods
2. Load the attached save
3. Enter editor mode and ensure "instant blueprint building" and "instant deconstruction" are enabled
4. Pipette a pipe
5. Ghost-place a pipe on an existing pipe with fluid
6. CTD

Thanks for the report. This is now fixed for the next release.

What was causing the issue? Was it attempting to set something fluid related on a ghost?

[Rseding91]

Yes. The new fluid functions didn’t reject adding fluid to ghosts.

Thanks, I'll make sure to look for that invalid code segment.
