What version are you playing? This was fixed ages ago as far as I am aware.
Viewing post in Voices of the Void 0.8.2 Bug Reports
That is an outdated version of 0.8.2, not even just it not being the latest update.
This should be a download for the latest 0.8.2 version, from the version archive website:

If you don't trust the direct link (fair), here's also the link to the website itself (linked on the main game page as "Old VotV versions archive", so this is officially endorsed). Find and download "pa0082_0012.7z" in the list:
