And I just realized - if anything like that happens again, please upload game log file, it can be very useful to determine why it happens. It can be found:
| macOS | ~/Library/Logs/All Parts Connected/Sipho/Player.log |
| Windows | C:\Users\username\AppData\LocalLow\All Parts Connected\Sipho\Player.log |
| Linux | ~/.config/unity3d/All Parts Connected/Sipho/Player.log |
