Unfortunately we have a bug in v1.5.0 which corrupts existing infoItems in the minutes collection.

before migration#23:

after migration#23

I pushed a hotfix on master & develop & docker image (v1.5.1 == latest) which simply skips migration step 23. But this will only help people that have not yet migrated...

For people that have migrated, we will provide a fix soon.
Seems the data is still there - not lost! - but format of data has changed so that 4Minitz currently can't use it.

Stay tuned. And: apologies!
