crash when sleeping in development branch

[pouar]

in the current master branch, when sleeping the game crashes, heres what it says in GDB
/usr/include/c++/4.9.0/debug/vector:357:error: attempt to subscript
container with out-of-bounds index 0, but container only holds 0
elements.

Objects involved in the operation:
sequence "this" @ 0x0x7fffffffae70 {
type = NSt7__debug6vectorI5dreamSaIS1_EEE;
}

Could enabling certain mutations from the cheat menu cause this? If this is the case then this might be entirely my fault.

[pouar]

Or could manually turning all these mutations to traits by manually editing the save file cause this. If so then this is definitely my fault.

It's possible conflicting mutations (more AND less sleep, heal AND take damage over time) might cause bugs, since they aren't designed for that.

But it's also possible that something borked. I don't have a lot of time right now to drill into it, but someone remind me and I'll check.
