Having trouble uploading a screenshot, but ran into an odd situation in my Sector 28, where there wasn't a warp point present. 'Luckily' there was a wormhole so there was some kind of exit. I'm not sure if that's allowed to happen occasionally or just luck that I wasn't trapped?
Can't edit the above post, but it happened again so I guess it was on purpose.
Better bug: The 'ESC to exit' button in the artefact identification screen can't be clicked - at least when the other options are 'positive' or 'negative' effect.
