The production problems with Sasayaku You ni wo Utau isn’t the first, but certainly won't be the last.
We know how disastrous Marchen Madchen's anime production was in 2018. It's a shame that any anime adaptation doesn't get at least a decent production that has a chance to possibly get another installment or sell more copies of the source material.
But instances like these won’t be the last, until something breaks or the workers decide to unionize. This is just not sustainable
