This afternoon I was playing Map #53 (Author: Creepermind). When the map was finished I clicked on the claim victory button and the game immediately froze and then crashed with the error "*** Error in `./ParticleFleet.x86_64': double free or corruption (out): 0x00007fe40547fe60 ***"
I'm attaching the full backtrace that appeared in my console.
I'm running Centos 7.2.1511 x86_64 and Particle Fleet v1.0.2b3.
If it repeats, you might have some luck by going to the advanced settings menu and turning "Use Synchronous Scene Loading".
These crashes like that are basically unity engine crashes and I have minimal control over them. I can manipulate what happens around scene loading at a high level, and that's about it.
It happened again this morning on a different map. Just now I changed the settings per your advice, and we'll see how it goes.
