I don't know why or how it happened, and it never happened again - but that day, the game wouldn't let me select the next stage and "forced" me to skip it, which is something you're normally not allowed or able to do.

Did this happen to anyone else?

PS: if the animation doesn't load, try to open the gif in a separate window / tab: https://lemmy.world/pictrs/image/19ab72f9-8805-4b2c-ada3-07e104900f83.gif
