I am doing the 'Don't fix if it isn't broken' approach.
I saw only issues here and in the slack channel with the 'new' 0.12.1.5 wallet while mine on the 0.12.20 are working as before.
and whole sequal is also weird...
i mean new wallet has core 12.1.5 and the old one has 12.2

to my knowledge 12.2 is newer than 12.1.5 ?? or am i wrong
