Rn the Flaze is extremely glitchy on the newest Linux version 
Because Flaze isn't supposed to be available in the game yet, you probably obtained her through a glitch. I remember finding this glitch some versions ago, but it's fixed now in the latest version (0.0.4.4). I'd recommend avoiding to use her until we reach v0.1, which is when she'll be officially available and fully functional. Maybe turn her into a primer just to avoid crashing during fights until then. I'm really sorry.
