Heylo mahomaho. Can you tell us what you were doing in the game when this error appeared? Thank you very much for reporting!
Oh I see. You must be using Linux, then? I just downloaded and tested out the Windows version and it's working fine, but I have no way of testing the Linux version. So I assume this is what is giving you trouble. I will try to contact Yellow and see if he knows what might be causing the error. Thanks again for reporting it.
