ZDoom

Just to make sure that you dont need any extra data from me.

My message was for all developers.

You talking to me or graf?

[b]DObject::Class[/b] pointer is null in [url=https://github.com/coelckers/gzdoom/blob/af5a2fe5225ca5b11c5fcdf9b488345a159f3871/src/serializer.cpp#L964]FSerializer::WriteObjects()[/url] function. Without heap it's impossible to figure out anything.

I spam save button until I became bored, ~30 minutes, and it not caused bug.
Unless it is related to track played on background, while I played gzdoom.

Its happened on very specific situation, without cheats, in room full of barons and knights. Just a temporary save in attempt to walk through room.
If saves from 3.7.2 dont work in 3.8 pre its takes some time to try to bug it again.

Does this also happen with a more recent build?

I play sunder, map 09 with bolter mod. Attempting to save game crash gzdoom.
