V14 (Version 14) etc. refer to the specific builds offered on Itch. It is listed on the game's page under each build. Currently, that's 'Version 18' for Linux, 'Version 15' for Win64, etc. There can be multiple builds for the same game version, so it can help to be specific when reporting bugs. V14 through 18 (and maybe V11-18) were all game version 0.5.2b, as you say, but only V18 fixes the issues in this thread. (For Mac, I believe V19 should have the same fix).
