Crash after failed quicksave
« on: September 06, 2014, 05:03:04 pm »
I quicksaved about the same time I was detected by the bot sentries under the Junkyard and the saved failed with the message popup saying the save cannot happen at this time but after that the screen was black and it crashed soon after. Some sort of race condition?

I think I found it. It should happen when you manage to issue a move command to the player just as it's about to save. Anyway, should be fixed in the next version.

It looks like you're not using a classical single threaded main loop style of programming to run the game. Well the drawback is you have to be very careful of race conditions. Good luck.

I am using a single thread, but multiple action are queued and executed in segments between processing inputs, rendering, etc, so they can sometimes mess up the game state for one another.
