It's hard to say if that situation is due to a glitch or was caused by unfortunate timing. Like most games, VV Origins 2 saves every few minutes. If you close the game before your recent activity has been saved, you may lose recent game progress. Without knowing more about the actions you took and the exact order and timing involved, it's impossible to know the cause.
